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

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.

They did, yes...

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.

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.

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:
where to all you other Brisbanites go to for your wheel alignments?

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.
