Wheel Alignment for D3/D4/RRS is not that simple!

[Roverworks Canberra]

Hi everyone,

We are Roverworks in Canberra(Richard, Johnny and Allen), and we'd like to formally introduce ourselves to the forum. Yes we are doing some advertising and marketing, but we'd like to contribute to the growth of this community as well.

Search results in Aulro don't show much about Wheel Alignment, and we'd like to share this article with you guys:

Wheel Alignment for Range Rover Discovery 3 & 4 (http://roverworks.com.au/news/wheel-alignment-range-rover-discovery-3-4/)

tl:dr Don't try to do it yourself! The calibration can get messed up if you don't use the proper diagnostic machine.

Your thoughts?

[nat_89]

Welcome to the forum, its an interesting topic for people getting wheel alignments for me my nearest LR centre is 6 hours away. I have heard on here that you put it on the machine and remove the fuse for the suspension and it will lock it in with no moments and go from there thats the best you can do when you can't get to a service centre for an alignment.

[tonyci]

very timely. i had some new tyres fitted the tyre dealer said i should also do a wheel alignment.I mentioned that it needed to be put into a special mode to do that. No problem they said we do land rovers all the time. Long story short it was not done properly and i had to go the a Land Rover Specialist to get it sorted.
So I agree.
Cheers
Tony

Welcome to the Forum guys, thank you for helping support the forum, if I was in the area, I would certainly give you guys a try, our local tyre guy is a great guy, I asked him about doing our car and flat out refused, stating he does not have the gear, let alone how to do it, there are a couple in the southern Sydney area that do know how to do it, which is good for us, hard to find someone good these days.

Also look at upcoming trips, there is a D3/D4/RRS weekend that is being held at Lake Lyell in Lithgow, maybe someone from your shop with a D3/D4/RRS could come, give a talk, sponsor the gathering in some way or just come and join in on the fun, terrible aren't I;)

some diagnostic units that are available can set tight tolerance mode for you. No reason why you couldn't set it in the carpark or at home before taking in for an alignment

[101RRS]

When I was getting my current tyres fitted at a well known tyre seller here in Canberra there was a D3 on the hoist.

When I asked about it they said it was going in for a wheel alignment - about 15km from the dealer. I asked if it had been put in to TTM and driven the 15km and they said no as was not necessary as they could lock the suspension. Assuming they met via a Nanocom or Faulmate I asked a bit more - well know.

There idea of locking the suspension was to lower it to access height and then use the height switch to lock it there and do the alignment at that height :o.

I attempted to explain that maybe that was not the right way to do it but their attitude was "we know boats" so were not interested in my thoughts.

But this does highlight some of the stupid things that LR do - in the UK you may be able to get these things done at the local LR dealer just around the corner but here and other markets where they are light on the ground it is not practicable. There should be an option in either the message centre or even on the height controller switch (like is available at access height) to lock the suspension in TTM with an override where it auto disengages over 20kph.

Though my RRS has now covered 90,000km and never had a wheel alignment and there is no indication it is needed. My experience with other vehicles has shown that where an alignment is done when not really needed it causes more issues afterwards.

The latest RRV & RRS with their new suspension ecu have a driver-selectable option to enter TTM, so LR have finally seen the light in this respect.

[shanegtr]

but their attitude was "we know boats" so were not interested in my thoughts.



no wonder they where doing it wrong:D

[catsman]

Local Beaurepairs in Footscray is one place where they have a flat alignment machine with the front wheels going on a turntable that is level with the floor. They tell me not many places have them but as it is level no adjustment to suspension is needed.

Not sure if alignment was any good as they said the way the tyres are worn it will take a while to even out and drive straight.

[Tombie]

Just a tool wheel aligners need...

Yes, but for an alignment shop...

About the same as a balancer mandrel

And, if I had one I would be promoting that I could do correct alignment procedures on LR vehicles and increase customer base!

[CaverD3]

Get an IID or Nanocom and add height calibration, steering angle sensor calibration etc. :BigThumb:

True! My MVS covers the bases nicely :)

Welcome aboard guys, it's quite a brave move and a double edged sword using social media as a marketing platform as while it may get you more business it also has the capability to ruin your credibility pretty quickly as well. There is a vendor on here who has taken advantage of it however and I don't think I have ever read a bad word about his business or the service he provides.
As an example I had my lower control arms done at an independant repairer the last time they needed doing at a cost of $1800 which was a reasonable price considering the difficulty of doing it at home and the genuine arms used. The invoice included a charge for a wheel alignment as well. When I got home and had a look underneath I was immediately suspicious of the white paint dots on the eccentric adjusters and started to wonder whether the wheel alignment had really been done or whether they had been lazy and figured it was close enough. Sure enough a couple of months later and two scrubbed front tyres the vehicle was booked back in for another wheel alignment at the repairer at my cost to get what should have been done properly the first time fixed at my expense.
Total cost - New control arms $1800.00
Two Tyres $700.00
Second wheel alignment $150.00

That experience made me reconsider the worth of paying for the arms to be done so this time I did the work myself and went to a small independant wheel aligner who contends that he has no problem doing a Disco and at a cost of $55.00 for a wheel alignment I can afford to monitor the tyre wear and go back and yell at him if its wrong.
My point being that if you advertise a service on a forum where people are much more likely to understand as much about as their vehicles as you do you "take them for a ride" at your own peril.
As a suggestion for a quick money spinner why don't you invest in a transmission oil exchange machine and offer full automatic oil changes (Mega Flushes) supplying Lifeguard oil at $50.00 a litre ( which you would still make a profit on at that price) I reckon you would have plenty of customers as you are offering a service that people on this forum know they need and is difficult to do without specialised equipment.

Good luck with your new venture

Tote

I agree with Tote using social media can be a double edged sword, good luck with it.

[mojo]

Interesting, I didn't know wheel alignments on D4's were such a specialised job. At my last service the dealer offered to do one for $130, but I knew the local tyre mob could do it for $70-$80. Now I'm not so sure!

Anyone know where to get one done in Brissie, preferably south side or close to the city?

Cheers
Sean

[~Rich~]

Most dealers / indies put the car in tight tolerance mode and drop them off to a tyre shop to get aligned, pick it back up and put it back to standard mode.

Im of the opinion much the same as yours, in this day and age business need to be online and have a big impact online as thats how to grow and get your business out there!! It certainly makes a big difference to be able to chat and tackle problems as they arise and deal with them as soon as possible.

To give an example when looking for someone to build an engagement ring for my partner and with a considerable budget to spend i had looked at quite a large jewellery name and was adamant they would do it, but one day looking through Facebook i saw a friend had like another new young jeweller in Brisbane just getting started so i made the call and chatted for half an hour what a great fella really nice and friendly and so helpful he did it all designed built and customer service and he picked up a great sale there from one call and i got more than i had bargained for in size of the diamond because i wasnt dealing with all the corporate side of it. Definitely recommend being online to any business!!

Not sure if anyone can help me but this does not look right????

I'm not sure

[ADMIRAL]

Hi Canaussie,

The rear toe is close to spec, but should have been altered to reduce the lh. The camber is miles out, side to side. ( the rear camber on the D4 is on the outer top arm. It is awkward to get to, and pretty much means 2 alignments, as you have to take the wheel off to access the adjuster . Looks like it was too much hassle for your aligner ) The lh front castor is normally up to 1/2 degree higher than the right. ( and yours was, looking at the previous figure ) This is to correct the natural tendency of most vehicles to fade left on cambered roads. Front wheel drives and all wheel drives are affected to a lesser degree. I guess the key question is , ' how does it drive ?' If it drives straight, I would not be too concerned.
I would be asking your aligner if they know how to complete a full 4 wheel alignment. If you want a good alignment, be prepared to pay.

[LiamO]

Hi Redback - can you please name a few of the southern Sydney Wheel Alignment shops? Have yet to find anyone who can actually get the steering wheel straight on my D2 (:

[LiamO]

That should be a D4 not D2 :)

[Canaussie]

It's driving nice and straight so no worries!!

[PaulGOz]

I think you can ignore there databank values they look like they are not d4 specific castor is to far out in their values. Also why would they give you toe out on the front? My understanding is front toe out will give you better turn in to a corner but will make the car feel like it is wandering in a straight line ok for a v8 super car but not the shopping trolley. Under acceleration this will tend to toe in and under braking it will toe out making it feel more darty. Also rear toe out is generally ok as it assists in creating oversteer which is nice for some and helps with turn in if required. Anyways that was what I gathered from my racing days in a tall heavy 4wd it may not be significant enough to be an issue. There was a previous post on the std wheel alignment specs you may find in a search.

Very handy information, good to see a business in Canberra that offers customer service, something sadly lacking in the majority of business' here.

Hey thanks tiddy!

I do hope you visit us in Mitchell when your Rover needs a checkup. Maybe you can share with us some tips on how to improve our services as well.

So In fairness I should admit that my small independant wheel aligner has no idea of what he is talking about.:o
A discussion that included the terms " we can see the camber bolts moving the arms in and out but it doesn't make any difference to the alignment" and the bolts must be frozen in the bushes and they are rotating" didn't inspire me with confidence.
So off it was to Rover Works who did a proper wheel alignment and now it steers like a Disco 3 again.....

That does not excuse the behavior of the other Independent mentioned in my thread though.

Thanks to the staff at Rover works for a job well done.

I wish Land Rover made it easier for smaller independents to be able to do an alignment as i live 3 hours away from one dealer and 6 from another just to much of a pain to drive there to get an alignment!! I guess my local ones are doing okay so far have 30000kms out of first set of tyres and still good tread left! But they should have a something to make it easy to put it in wheel alignment mode or something like that.

[nismine01]

Quote; Re Disco 3 & 4s "presents an issue if you try to have a wheel alignment done by the guy at the tyre shop." :mad:

Ha, you gotta be joking, I don't know a tyre shop that does wheel alignments on 4X$s, :o they charge you for one but only do toe in adjustments, I asked before my last one. :mad:

Mike

[Blknight.aus]

as an interesting side line.

while you shouldnt adjust the suspension/steering on a D3+ (or rangie equivelent tech vehicle) you can still do a field check on the alignement with the old school string system...

Adjust no, Check yes.

you have to be a lot more detailed in your setup BUT, if you slab is flat and level you can create a base line for the vehicle and then check it against itself later...

improvised in the field it can also help you identify some faults if your handling has gone a little "off" after an off road session. a 3mm change in the camber of one wheel you might not spot by eye but with a string line measure up you'll spot it. But again, all it lets you do is Identify that you have a problem, it doesnt mean you can fix it.

-----Currently unsponsered blurb here..

I suspect that given whats on the website, and some of the R/C I've heard
from a few different latte consuming types from some forums that people not in my line of employment cant get into if I get that way inclined while Im going quetly insane at wagga I might be making a visit over to canberra for a look see at a certain workshop.

I've got a blown bulb and from what I hear this place might just be the souths answer to MR auto, they just dont do properly old stuff...

short version of that.

I've heard good things about these guys on sources I have good reason to trust.

[catch-22]

An old thread but better than starting new.

Had the wheels aligned as it would veer left when the steering was held straight or there was no light force to the right. Very very annoying

Two alignments and a swap in front wheels and it's still veering left...

Asked about whether the workshop had a TTM - "a what?". nuff said.

103880

Probably have to take it to a dealer but I've had mixed results there as well.

I'm on the North Shore of Sydney so any advice on where to go that follows the correct procedures for proper alignment would be great....

[scomac]

Had a wheel alignment, rotation and balance done at Tyre Power Osborne Park for $100. They know what they are doing and do great job, that's why I have been going there for about 15 years with Land Rovers.

[catch-22]

Thanks Scomac. 3963k's is a little far though..:D

Simply mistake I know......but $100 sounds real cheap for the detail i've read about in this thread...

On the next corner from Trivett LR service, Parramatta (River Rd West), is a tyre place (whose name I can't remember :( ). I think that they may be part of the Trivett Group. It may be worth contacting Trivett LR service and getting contact details.

I only used them once, but was very happy with the results.

Best of Luck,

[Plane Fixer]

I recently had mine done at my local dealer (Belbowrie) after I replaced both front lower wishbones.
They did a fantastic job as the car now tracks straight and true, where before it had a very slight tendency to pull left.
It proves that the correct way is TTM and LR specs. I was given the alignment before and after print out.

I have gone to Pacific Motors Pymble for this to be done and they say they know about TTM. I trust them.

When I queried Tyrepower in Artarmon they said they would put it in TTM. I am not sure whether I trust them.

I agree with Andrew - Cremorne Prestige (actually located in Hotham Parade, Artarmon) would know what they are talking about. I would trust them.

[catch-22]

Of course. I used Greg with the D2 once. I'll give him a call.

[catch-22]

..end result, back to Land Rover for another alignment......hopefully they work it out..

[catch-22]

OK, my car is fixed.

Taking it to someone who know these cars is essential.

Learner was right in his post above...

Note that I've been to two dealers and a specialist LR 'professional' who often gets recommended on this site (above), non of whom picked up that the caster was out by 180 degrees and the geometry was setup all wrong. They all tried to compensate for this basic oversight.

If you're in Sydney, take your Disco to Jim and Glen at Tyreright in Parramatta (who Learner recommended above). Worth the drive.

My Disco tracks perfect now and they've won a customer for life.

Shame I had to spend my hard earned on the others...

[NomadicD3]

hmm well isn't this interesting...
I will be needing a wheel alignment soon due to replacing a front wheel bearing. I have just spoken to a tyre company that "specialises" in land rovers with EAS and was emphatically told that TTM was not required and in fact TTM is detrimental to setting up a accurate wheel alignment?? They also claim they do about 20 vehicles a week with EAS.....hmmmmm comments???

[catch-22]

TTM is most certainly required. Glen from Tyreright made a point of letting me know he was going to connect the tool to put it in to TTM. Even showed me the tool.

I just went for another drive, man what a difference. So good to have this fixed...

I would be avoiding this so called "specialist" like the plague. You don't have to look too hard at all to find out for yourself that they are talking out of their arse. ;)

[Graeme]

I will be needing a wheel alignment soon due to replacing a front wheel bearing.Replacement of a wheel bearing does not ordinarily necessitate a wheel alignment.

[NomadicD3]

Graeme - yes correct mate, It's replacing the front top control arm bushes is why it will need a wheel alignment. Apologies mate but thank you..

BM- agree, but the concerning part is apparently they've been doing it that way for 3 years!!!

Catch-22, Now that is interesting, same tyre chain and the one I'm referring to is associated with the LR dealership and do all their cars. It's the one on the northside, for the locals LOL...

I'd say they are full of pooh. The whole point of TTM is to set the car at the correct Null point.

A mate of mine was recently told by another 'specialist' that he knew how to align Discos with EAS. His solution was to open the door while the car was running and then switch it off. I'd have demanded my friggin money back!

Good point actually. I should demand my money back from the ones mentioned who didn't pick up on a basic alignment requirement.

Technically they have made false or misleading statements regarding their ability to do the job.

And maybe in normal cases they could claim it's their word against yours but in this case the fact that they don't have the equipment to actually do the job should speak for itself.

[catch-22]

They had the equipment. They just don't have the knowledge. Even after going back three times they kept trying to compensate rather than search for some other reason as to why it was still not right. Ohh well, live and learn.

[NomadicD3]

Ok this is getting hilarious!!!!
Phoned 8 different tyre and or suspension shops. Asked the simple question.
Do you put vehicles with EAS into tight tolerance mode when doing a wheel alignment.
6 responded with HUH!!! or What or, my favorite, never heard of it!!!
1 responded, as previous stated, no as it's better not too.
1 responded with yes we do........ well kind of... we leave the door open and the suspension can't move.
Now I realise that the last has been stated before but what is really interesting about that one, is that is the company that the other LR dealership uses for all their wheel alignments IE the one on the southside, for the locals.
Now who'd have thought getting a wheel alignment would be so difficult LOL

PS_ The southside dealership is of the understanding that the company that does their wheel alignments does put it into TTM

Yes,that is what most do around here,not just with LR vehicles,but also Audi,BMW,etc,anything with EAS.

[catch-22]

They did, yes...

[Celtoid]

I was surprised that even in the Brissy CBD, they don't do their own alignments....


I thought the idea to compensate if you went to LR for an alignment, was that they would put it in TTM (if the company they use hasn't the kit) before taking it somewhere else for the alignment using the data supplied by LR.

[Celtoid]

They did, yes...


OK, sorry, must have mis-read.


I thought that they not only didn't understand the LR data and didn't do a proper TTM.

[Graeme]

was emphatically told that TTM was not required and in fact TTM is detrimental to setting up a accurate wheel alignment??TTM reduces the acceptable variation from the target height from around +/- 10mm to around +/-3mm but does not change the target height. Setting TTM cannot possibly be detrimental because if not set then the vehicle could be acceptably low on 1 side and acceptably high on the other with up to 20mm variation between sides.

Agreed. You can complete an alignment without TTM, but it may not be as accurate. A lot of owners are quite happy with their non TTM alignments. It is up to the individual as to what you are prepared to accept.

Probably be the tyres (READ - uneven wear) that will advertise the accuracy of the Non-TTM Alignment and will dictate how happy the owners are with that stance ....

How could you possible know what the right height or level is on the suspension when it gets artificially locked mid-stream on a surface of an unknown level .... (which I believe by my reading won't actually occur by just opening doors, etc .... in other words it doesn't completely stop the movement)?

Hi Guys
will be getting my new 19" Hankooks fitted in a week and now i am very confused where to get the wheel alignment done. I do have a Nanocom but when i tried it out in the shed not much happened, i could still change the height with the switch :confused:

That would be as I expect. See Graeme's post above. ;)

The switch on the console changes the "target" height (access / normal / off-road) - this is not affected by entering TTM.

When you enter TTM, you decrease the allowable tolerance at whatever "target" height you have selected. If you are not in TTM, the vehicle can be at the selected "target" height, +/- 10mm. When you are in TTM, the vehicle will be at the selected "target" height +/- 3mm.

I would assume that the correct settings for wheel alignment would be at "normal" target height, in TTM - so is at +/- 3mm from the vehicle's "normal" highway travelling height.

This is my understanding of how it works anyway - I'm sure that someone will correct me if I'm wrong.

Thanks for that. Another reason why I will not take my D4 to that dealership. ;)

The other dealership actually puts the vehicle into TTM themselves at "normal" height, and then delivers the vehicle to the nearby wheel alignment business - with the dealership then unlocking TTM once the work has been completed. Mine is booked in for this in a couple of weeks, when the control arms are being done along with 120k service.

[Ghost-Who-Walks]

Such a fascinating thread. I learn so much on this forum!

My recent experience below - which after reading this thread, is not ideal!

I had 2 new tyres fitted to my D4. When I asked the them about doing a wheel alignment, they gave me no confidence that they understood about any 'special' procedures for aligning EAS vehicles. Note, I did not specifically ask whether they used TTM when aligning, only if they used any special techniques or modes during the alignment process.

So, after some research on here (love this forum), I booked it into one of the tyre specialists that people had recommended. Very friendly, and seemed to be knowledgeable. They do a lot of LR alignments for a nearby mechanic. I got a nice printout of before/after measurements etc etc.

When picking the D4 up, I asked the manager "how he made sure the vehicle was 'at the right height', because a lot places don't do anything special with EAS vehicles".
The answer...

"I leave the car running while I do the alignment, that way you know it's going to maintain the right height"!!

Based on the comments above, it may be 'roughly the right height', but the tolerance of that height will be +/-10mm, as opposed to +/-3mm in TTM!!

So, I guess my options are either to get another alignment ($$'s), or monitor for uneven wear and act based on that (possible $$$'s)!!

Thanks for the info

Again, so much knowledge on this forum, let me ask a stupid question as a flat earther,surely there is a non ambiguous procedure in the relevant service manual that can be waved at the technician.

Makes me appreciate the Defender approach,

It's a bit of a same to hear this as I was going to use this guy for my next one (coming up, with new LCA and tyres scheduled in the next month). For my previous one, I used a local guy to me. He didn't seem to know much about it but said he had the aligner that used to do them for the north side dealer. Car has driven well but drivers rear has worn on the inside down to the canvas while the rest of the tyres are still OKish. I was keen to get a better job done this time. Might be the north side dealer........

[Graeme]

..surely there is a non ambiguous procedure in the relevant service manual that can be waved at the technician.IMO LR were remiss in thinking that owners would always take their vehicle to a LR dealer for any work where diagnostic equipment would be available to set TTM but at least have now corrected the situation and provided a driver-initiated procedure to set TTM in the L405 and L494 owner handbooks.

[Celtoid]

This is what EVERY LR Dealership should be doing if they can't do the alignment themselves (not sure if any do). They should put it in TTM and then send it round the corner to the alignment place that has actually had some dialog with the Dealership regarding he correct settings. Alignment guy then sends car back to LR for TTM unlock.


It is possible I suppose that some places that do work for LR don't realise that the car is in TTM when it comes to them. As long as they have the correct settings for the alignment, I guess it shouldn't matter. However, if this innocent ignorance is present, it is possible that the aligner now thinks he can 'do' LRs and offers that service direct to customers, with the TTM never being done.


If they attempt a DIY TTM without a plug in device they are either pulling a shonky or they are ill-informed. In either case I wouldn't let them touch my car.


I've spent a lot of money on my car, I know my local LR does follow the correct TTM set-up before sending to tyre place .... so I just go there.


It's really not that complicated. If the dealership is not doing a TTM, surely they should be getting reported to JLRA?


I am considering getting a device so that I can do my own TTM settings (amongst other things), as I know a couple of local tyre guys that I trust that always do a great job on my wife's sedan.

It's a start Graeme but what about us poor D4 owners? Are there plans to affect this across the whole air-suspended range do you know?


I'm assuming something had to be modified in the two Rangies to allow this procedure to work and that it wasn't always possible but just never publicised/printed?

[Graeme]

The L405 & L494 have a physically different "dynamic suspension" ecu that can contain both the suspension and CVD logic if the vehicle is fitted with CVDs. It has other improvements such as 2 off-road heights with a higher speed limit of 80 kph for OR1, although IMO a poor implementation as OR1 is not selectable per se. OR1 is only 35mm in the RRs or 40mm in the RR and OR2 is 65/75mm for RRS/RR with a 50 kph limit.

I would not expect LR to ever add the extra capabilities to the earlier version ecus.

[DazzaTD5]

When I first started taking D3s to Bob Jane tyres in Vic Park (W.A) and had said its in the required mode, they looked at me blank, after I explained it, they said "that makes sense" Now when they ask all customers that bring in D3, D4, RRS if its in its correct mode... they now get the blank looks...

As for the social media / club thing...
Personally I don't see it as a double edge sword, if you are doing or trying to do the right thing by customers as a normal part of your business then dedicated forums and 4wd clubs will always be a good source of business.

[laughto]

They had the equipment. They just don't have the knowledge. Even after going back three times they kept trying to compensate rather than search for some other reason as to why it was still not right. Ohh well, live and learn.

So this was at the Land Rover specialist on the Lower North Shore - referred to above?

As I said what does the service manual say

Sure is.

[SBD4]

As I said what does the service manual say
Here ya go wantok, refer to step 6:

[Narangga]

The D3 has always wandered to the left ever since I got it.

After a new steering rack and replaced control arm bushes it was terrible. Almost did a left hand turn when you let go of the wheel. Had a different place do an alignment after I received my Nanocom and so was able to put it in TTM. Better but still not as good as when I picked it up.

Had two new tyres put on today and they also did a full alignment - results attached.

It still takes pressure to the right to keep the vehicle tracking straight so that it does not wander to the left. Possibly as it was when I bought the vehicle.

However, is it possible to get it to track straight down the road in the same way my D2 did? And yes I am driving the same sections of road to compare both vehicles.

[vbrab]

I have to get my D3 re-aligned every time we change over front end/steering parts (and it has had at least 3 sets of lower control arms), and usually have to rely on local country aligner with a 4 wheel laser aligner, who rarely sees a Land Rover, but manages to do a pretty good job of aligning.
Seems that he always leaves the drivers door slightly open, once vehicle is set up to start the alignment. Says leaving the door ajar stops the suspension altering itself while he is making adjustments.
His alignments seem to work pretty well, and the vehicle drives straight and tyres don't get excess wear on tyre edges.
HOWEVER. alignment done by LR aligner "expert" in city, managed to rip through to canvas on inner edges of new rear tyres in under 3000 k's. I did a visual self align with a large crescent that got me out of trouble until could get it back to local "amateur'.
If you find an aligner who can do a competent alignment on your D series, stick with them.

[Narangga]

Amen to that!

Glad you at least get something reasonable where you are.

[Geedublya]

Sure is.

These experts charged me $300 for an alignment when I changed out my LCAs. A few days later I got steering angle errors and re-calibrated it myself using my IID tool.
It was only because my regular indy was unavailable that I went there.

[NomadicD3]

Hi All,
Well another day another comical conversation.
Due to my complete inability to just let things go {one of my many character flaws}, I have had several conversations with the local ?Landrover wheel alignment specialists?, over the last couple of weeks. This is the specialist on the north side of Perth that's owned by the local land rover dealership and does all the nearby dealerships vehicles. Today's conversation was by far the funniest.
This company had done a wheel alignment on my vehicle some time ago, which resulted in the inner edge of front tyres being worn to the point of being nearly illegal but with over 6mm of tread on the remainder of the tyre. By way of proof I returned to them today with one of the worn tyres and had an extensive conversation about the use of TTM during which their representative repeatedly said ?we have never put any vehicle into TTM? and continued on with many stories of how people have never complained about the wheel alignment s that they have done and in fact have received many compliments on the extra mileage their clients have got out of the tyres due to the accuracy of their wheel alignments. When I pressed them on what the Land rover manual clearly states as the correct procedure for doing wheel alignments I got a response that I can truly say I never expected. The representative's response was, and I quote ?WE DON?T WORK FOR LAND ROVER, SO WE WOULD HAVE NO IDEA WHAT THE MANUAL WOULD SAY?. This took me by such a surprise that I just stood there looking at him and went ?HUH? at which point he repeated the statement verbatim. Now remember this is the primary wheel alignment specialist for the dealership around the corner!!! It was at this point I recalled the old saying about getting into a battle of wits and quietly left.
Final thought ? This really is NOT the rite tyre place!!!

SO now for my stupid question- Mostly aimed at Graeme.
If you were to park the vehicle on level ground and pull the main suspension fuse in the engine bay, that would prevent any movement, would that effectively be the same as TTM?

Hi mate. I'm getting new tyres fitted this week so am just about to delve into my Nanocom to see if I can find a TTM setting......

Re your question, sure pulling the fuse will stop any movement, but it will not help if the vehicle is not at the right height in the first place. Doesn't TTM adjust the corner heights to a tighter tolerance, pulling the fuse will not help this at all?

[BMKal]

If you park the vehicle on flat, level ground and let it "find its level" before pulling the fuse, each wheel will be at the selected suspension height (assume "normal" height) +/- 10mm. TTM will see the suspension adjust to the selected height, with each wheel being at the selected height +/- 3mm.

[LandyAndy]

If one is spending a fortune on tyres at a dealer owned tyre franchise surely one expects its done correctly.
They admit not doing TTM I would be going into the dealership that owns them and asking questions and wanting a deal on the replacement tyres.How many Ks to ruin the tyres???

[JamesH]

I'm listening to the rain falling down outside and I know that 58000km off the originals is all I can reasonably expect and it's time for me to get the credit card out if the rain has set in for the year .

$357 per tyre from BJ Osborne Park for Hankooks seems to be as good as I'm likely to get.

I believe they can fit them (after I tell them to be careful with the spare tyrewinch and not use a rattle gun on it) but should I get an alignment as a matter of course?

Normally I would but if it's going to make things worse because it's not done properly then should I leave well enough alone if Ive got no obvious symptoms of mis-alignment?

This thread gave me the fear.

[rar110]

I didn't need an alignment when I bought new tyres for the L322. That was about a year ago.

Thanks Andrew. FYI I've made an enquiry with BJ Osborne Park. I asked them if I needed to get the car set to TTM at Barb's before dropping it in. They said they do lots of D4s and have no issues and charge the standard $75.

I interpreted this as they do not set to TTM. Which concerns me, but I'm not an expert obviously.

I'll check the tyres as you say nd leave well enough alone I reckon.

As BMKal and others have pointed out, the best they can hope for in this case is +/- 10mm. The what ifs are to do with all the variables of getting the car on something completely level and actually being sure that the car has fully adjusted to that level. Of course +/- 10mm does actually cover the +/- 3mm of TTM, so they might be lucky and arse it by locking the car within the range of the TTM.

[BMKal]

James, apparently there's a tyre / wheel alignment place in Osborne Park somewhere near Barbagallo's which has the equipment on site to put your vehicle in TTM for wheel alignments. Not sure who it is, but it is where Barbagallo send vehicles for wheel alignment.

Mine was done a couple of weeks ago after they did the front control arms. When I asked the service manager at Barbagallo if they put it in TTM before taking it round for wheel alignment, I was told that they didn't need to, as the wheel aligner they use has the correct equipment and could do it on site.

If you know anyone at Barbagallo, they might tell you who they use. I deal with Curvin MacDonald at Barbagallo (or Hamish if Curvin is not around).

Mine will be back in there next Tuesday as they have to repair an oil leak in the transmission. Getting a full service done and fitting the steel pan upgrade while I'm down there for a couple of meetings for work.

If you get your vehicle serviced at Barbagallo and speak nicely with them, you might even score one of these to take home with you. ;)

Hi Eddy, thanks for that. Ive dealt with them before when I had the Defender, good people, and they are within walking distance of my home. I was only inquiring at Ossie Park because I assumed they were very familiar with D4s as I'm sure they are.

If youve used Wellington St and they did a good job, then I'll definitely give them a call.

Hi BM,
I hate to do this to you mate but the company I've been referring to in all my posts is the same company that you've been told put the vehicle into TTM themselves and if you read my previous post it covers their veiws on TTM.

Does the car indicate that it's in TTM? I've never seen it done but maybe some advisory light appears on the dash?

[Narangga]

Page 99 of the owner's manual describes what should be seen at startup.

It is a vehicle with an arrow inside it pointing down. On top are two curved arrows - one pointing left, the other pointing right.

Well it is on my MY06 anyway.

[LRD414]

Does the car indicate that it's in TTM? I've never seen it done but maybe some advisory light appears on the dash?

Yes it does. A warning that vehicle is not in customer mode or words to that effect. Saw it when I have put D4s into TTM with iiDTool.

So there shouldn't be any confusion then one would think?


If a tyre place doesn't know that there is an actual visual indication for TTM, he probably shouldn't be touching your car.

[Danzig]

if you leave drivers door open the car does not self adjust suspension again until door closes. It’s a good way to find a leak in air bag as car will sag and not correct if one of the airbags are leaking. Also I imagine it may help when wheel alignment is being carried out to stop air suspension from moving.

I've been told this by numerous people - so have no reason to doubt it... Even my recommended wheel alignment specialist said that was how he stopped the suspension adjusting during alignment.

However I have had multiple examples where the family have got out of my vehicle, and i can hear air being released from the suspension, while the doors are still open.
Is that not 'adjusting the suspension'??

Personally, just need to put it in TTM, and give it to the tyre shop to do the alignment. Saves on all the questions...

Rob

[Danzig]

I think it’s driver’s door only that stops it adjusting not sure about other doors. I guess putting it in ttm mode is the best option if you have diagnostics access.

Not correct. It can/will move. And can be up to 20mm variation side to side/front to rear.

[DieselLSE]

Selective quotes from the Workshop Manual:

Height changes are also restricted for safety reasons, when a door is opened and the vehicle is stationary for example.

Vehicle height changes are restricted if the air suspension control module receives a 'Door Open' signal and the speed is less than 5 mph (8 km/h)

Ride Height Tolerance Control
The air suspension control module has two ride height tolerance bands; normal tolerance and tight tolerance.The control module considers the vehicle to be at target height if the current height is within the appropriate tolerance band. Height adjustments are not made until the vehicle height falls outside of the tolerance band for a pre-determined time. The time period is different depending on if the vehicle is moving or stationary. The tolerance bands are as follows:
Normal ± 10 mm
Tight ± 3 mm.
The tight tolerance band is only used if set by the Land Rover approved diagnostic system for diagnostic purposes or when the vehicle has been stationary for more than 5 minutes.

Door Open Inhibit Mode
If one or more of the vehicle doors are opened during a height change when the vehicle is stationary, the air suspension control module will restrict further height change.The LED on the air suspension LED display for the target mode height will remain illuminated and the raising or lowering LED will flash.If all of the doors are closed within 90 seconds, the height change will resume. If the 90 second period is exceeded,the message 'CONFIRM REQUIRED SUSPENSION HEIGHT' will be displayed in the IC.

Periodic Leveling Mode
When the vehicle is parked, the air suspension control module 'wakes up' two hours after the ignition was last switched off and then once every twenty four hours. The vehicle height is checked and if the vehicle is not level within a pre-set tolerance, small downwards height adjustments may be made automatically.

And from the wheel alignment section:

6. Vehicles with dynamic suspension: Using the diagnostic tool, set vehicle to 'Geometry Set Mode', using the instructions below. Putting the vehicle into this mode will make sure that the ride heights are controlled more accurately.
1. Select the 'Configuration' tab
2. Select 'Set up and Configure'.
3. Select 'Air Suspension'.
4. Select 'Suspension Geometry Set Up'.
5. Select 'Tight Tolerance Mode'.
6. Follow the on-screen instructions until the set up process has finished.

[101RRS]

I can assure you that is not the case - it will adjust with the door open. I do not have the muffler fitted to the exhaust on my air compressor so easily hear it when air is being released - jack up one side of the car with the door open and the system adjusts all the way.

[101RRS]

If the 90 second period is exceeded,the message 'CONFIRM REQUIRED SUSPENSION HEIGHT' will be displayed in the IC.



This refers to physical height changes such as changing from onroad to offroad height or lowering etc via the console switch - it does not apply to self leveling functions.

[Tombie]

Having seen it do it on several vehicles I wouldn’t rely on it.

And as mentioned with a potential of up to 20mm variance in height I wouldn’t be aligning it like that either.

[Celtoid]

I don’t think anybody has ever mentioned or knows this and it could be pure conjecture on my part.

During normal operation the car tries to level relative to the surface that its sitting on. Is that correct?

In order for TTM to get as close to the null point as possible, it would have to be effectively referencing to itself (car), regardless of the terrain, wouldn’t it?

Which practically means when movement is forced to stop by means other than TTM you could have all 4 legs as much as 20mm from the null point, in either direction I suppose .... with a total potential complete separation of 40mm between two wheels. That can’t be great for the wheel alignment.

This thought has only occurred to me and it maybe completely wrong LOL!!!

Thoughts?

[DiscoDB]

I have read this in several places in LR’s own material.

Opening the door during a height change (i.e. when it is changing to a new height) will stop the height change.

However, levelling (which is technically not a height change) can still take place even if the door is open.

Leaving the door open does not stop self levelling.

You're overthinking this Celtoid.
We're talking wheel alignment here and you're not going to attempt that half way across a paddock. At some stage before the wheel alignment, and this could be miles away perhaps, you set the suspension to TTL. There'll be a warning on the dash that the car is not in customer mode or something but the car will drive to the alignment place quite OK. At the aligners they will place the car on a supposedly level surface and the car will level itself to within 3mm of spec at each corner. It should then be sitting as perfectly level as it can. It will adjust itself as the driver exits or whatever. Thus the alignment will be as accurate as possible.
After the alignment, reset it back to normal mode.
I make sure I have the main tank full and auxiliary tank half full and that the car is loaded with what I normally have in it before doing an alignment.

At the aligners they will place the car on a supposedly level surface and the car will level itself to within 3mm of spec at each corner. It should then be sitting as perfectly level as it can. It will adjust itself as the driver exits or whatever. Thus the alignment will be as accurate as possible.
After the alignment, reset it back to normal mode.
I make sure I have the main tank full and auxiliary tank half full and that the car is loaded with what I normally have in it before doing an alignment.

Probably am ... LOL.
