D4 - a little bit of steering wheel wobble under brakes.

[GregMilner]

G'day folks (and folkettes in case there are ladies reading) - I've noticed a little bit of steering wheel wobble under brakes at highway speeds lately. 2016 D4 SDV6 has done 78,000km, had new brake rotors and pads less than 10,000km ago, my local indy LR specialist tells me it's the front lower control arms need replacing.
I'm not really doubting him, and the car has done a bit of serious off-roading in its life. Just wondering if anyone else has had the same issue and did replacing the LCAs fix it?

[Tombie]

It’s one of the symptoms.

You can check them both visually and with a pry bar - give them a “wobble” and see how far gone they are.

Thanks Tombie, I thought as much.

Yes and yes!

[josh.huber]

I'm at the same point. I've got bushes. But I had to get rid of the press a while ago. No room. Debating whether to buy an on vehicle press

Yeah but you have to lay on the floor. Hard to drink beer like that compared to using a h frame press

Same problem! At anything over about 70kph I get the wobble. Less than and it’s not too bad. Current LCA bushes are 100,000km old. Checking them they don’t look too bad - don’t move a lot and no leaks, but I’ve never levered a new one so hard to compare.

If my old frame can do that anyone can [emoji6]
And it’s Jacks for car / bike work.
And then a quality Scotch after the jobs all done.

Next time I do mine it will be easier as the hoist is due soon [emoji41]

Re hoist...do not buy a cheap chinese one..go for quality eg Rotary or Ben Pac(?). Local installer has a shed full of condemned cheapies that had various failures..largely due to weak frames.

Yes Rotary do manufature in Asia too.. but they are much better quality.

[dirvine]

Just a question I have an old 10T H press. Will that be powerfull enough to remove the bushes?

I am on the same boat with my steering wobbles when braking at high speed.

I dont think I will be attempting fixing it myself any reputable rover shop in sydney anyone can recommend ? also what will be the rough estimate of replacement ?

cheers guys

Just make sure it's not the rotors..mine was suspect LCAs but since replacing the rotors n pads all around... alls good.

Sure thing . I will double check everything before doing the Lca . I am suspecting it’s the rotor and the pads

[GregMilner]

I put new DBA rotors in late last year plus new pads, so I'm guessing it can't be that, unless of course the rotors have warped for some reason. Unlikely though. A new pair of LCAs looks like being about $400 plus labour, so I'm expecting a quote for at least $800.

LCAs are closer to $480 a side retail. A bit more if the bolts need replacing. (LR insist that the bolts should be replaced, but they say that for about every bolt anyway). If all goes well fitting should be about two hours a side plus a wheel alignment. An all up quote of around $1,200 would be reasonable.

Er, yes, you're right. I must have been looking with only one eye on the eBay site. Just got the quote, $1,272 not including wheel alignment. The indy also suggests there's a "heavy duty" option for another $100 a site, but I've never heard of such a thing. I would think the standard LCAs for a D4 are pretty heavy duty anyway.

Not for a 2016 model I wouldn't think. There is probably a heavy duty version for armoured vehicles, but that would need more research. I'm pretty sure the D4 versions were upgraded from the D3 ones and that D3 users would fit them as an option. Best to check your VIN with a dealer.

Heavy duty ones Greg are a revised rear bushing, less flexibility however not as rigid as a poly bush. I have used a few and been happy with the results.

Justinc, are these OEM or aftermarket?

[justinc]

Aftermarket/OEM. The brand is Meyle.

Yeah Justin, they came back to me and said the heavy duty option was for solid bushes, with a somewhat harsher ride, I'm going to stick with the fluid filled ones.

cheers guysI would talk to Ward at Graeme Cooper Automotive at St Peter's. Looks after both my D4 and FR2

[GregMilner]

Had the LCAs done and all seems good now. Had to do a wheel alignment though as the steering wheel was noticeably down on the right. (And even after two previous alignments at the same shop in Busselton, they STILL gave me strange looks when I insisted putting the car into TTM, and insisted the technician NOT leave the door open during the process.)
just towed the two ton camper trailer down to Molloy Island for the weekend, everything running straight and true and no more wheel wobble under brakes.
Now for our fishing trip to Exmouth next week, a lazy 3,000km round trip in 10 days:)

Just a little update . I have change both front rotors and the pad to the dba slotted and their extreme pad which seen to fix the problem now however the pad feels a little loose whenever I hit a bump or in even surface it will make these clunking noise . Anyone experiencing similar problem with their aftermarket pad ?

So, mine got so bad that my steering wheel was moving and inch in each direction. I bought discs thinking it was them that are sitting here and then this week I looked under and saw the telltale leak of fluid from my LCA bushes. Since ordered AF KIT630 HD arms with HD Mehle bushes. Discs will be used if required too. Will start with arms.

DJ, you’re gonna need to change your signature to “2020 TDV6 3.0L Discovery 4 HSE” with all the bits replaced recently.

seriously, whilst there, I’d be doing discs anyway. Hope you didn’t get DBAs, mine lasted 60,000km with Bendix HD 4WD pads.

I went with RDA this time. Lord knows.

And yes, lord help me. It’s a damn brand new car at this rate.

Saw a new Defender drive by yesterday. Jealousy!

Bendix HD will shred any rotor.

So took my car back to my mechanic (not the same guy fitted my brake pads and rotor) apparently he have seen the rattle sound from the brake pads before and he mention that even on genuine pads as well . Pad has a little play in them so when u hit a bump with out braking and pad has a small play solution given was either try a set of pads or using high temp silicon bond the pad to the callipers . Well since the pad is brand new I went with second options . Picked up the car couple of hours later noise gone . So it was the pad rattling not my control arm bushes . However he mention that my rear arm bushs is on the way out anyway . Still running original arm since new . 1700000kms now so I may look into arm replacement soon .

Hi all - following this thread with great interest. I have a MY16.5 SDV6 landmark that currently has a slight wobble under brakes, history is as follows:

- 55,000km rear pads replaced at Ritter, rotors deemed fine and told front will be due at next service
- 62,000km approx developed severe wheel wobble at high speed under brakes, classic warped rotor signs so I had the font rotors replaced at my indy garage. Used DBA T2 4x4 Slotted rotors and Bremtec pad after reading thread on here. Braking performance is fine with these ad mayeb a little less dust than standard. Rotors also look good with black coating on hubs.
- At this service I asked them to check the LCA bushes and they said 'they require replacement but not urgent'
- 64,000km slight wobble under braking returned, seems to be more at slow speed, sometimes through the wheel but also felt through chassis / seat
- took it back to the indy who did a test drive and suggested it could be the rear rotors

I have ordered rear rotors, again DBA T2 slotted as they will need doing anyhow but reading this thread probably needs the LCAs done too? Thoughts?

Anyhow I'll get them done and post up the results. The LCA is really disappointing, our disco hasn't missed a beat otherwise and in my view you shouldn't be changing suspension components, in what is meant ti be a heavy duty vehicle, at 60,000km!

Cheers

[Eric SDV6SE]

Front LCA's are characterised by a clunk under braking or when going over a speed bump.

Uppers (front and rear) rarely wear out. Rear lowers would be similar to fronts, but also not common.

The front LCA's take the most load. The Mehle hd bush and arm kit are the best value, easier to replace the whole arm.

Hi Factory


I recently bought a 2010 D4 3.0 and it came with a slight brake shudder. Inspections by the dealer, and an independent, advised that the brakes were all good and well within tolerance.

Further research came up with the idea that the pads were indeed depositing stuff onto the rotors, and the cure was as simple as several very hard stops from 80-100kph.

After trying to put my wife and I through the windscreen a few times, the brakes now have considerably less shudder and I think a few more heavy stops should completely cure the problem

Worth trying first as it is a cheap fix!

Regards
Trevor

Thanks Trevor, interesting. When I was researching the topic, I cam across this THE REAL TRUTH ABOUT WARPED BRAKE ROTORS.. (https://alconkits.com/support/brake-pad-info/110-the-real-truth-about-warped-brake-rotors) which supports what you are saying, I'll give it a try.

Cheers

[scarry]

Slight shudder on mine when braking at speed on occasions,it’s definitely worn LCA bushes.

[josh.huber]

I just did rear rotors and pads and cleared up some wheel wobble.. Which is suprising as my lca are definitely due. Pads were genuine just approaching the sensor

[Benji786]

I had the same shudder when braking (both at low and also high died), and also have the clunking sound when going over small bumps. I have a 2008 D3 Diesel.

Took the D3 to my local LR specialist here in Sydney, and got the front discs, pads and sensor replaced for $505. They also confirmed i need new LCA replaced.

They quoted me $1300 which includes the replacement of the sway bar bushes which they say should be done given they are working in that area anyway.

Thanks for reading.

[DiscoJeffster]

Replaced both front arms today with Mehle HD (for those that don’t know, they use the solid rubber rear bush in place of the hydrabush, and not poly either).
New bolts with copper grease FWIW.

Brake wobble gone. Knocks and rattles also gone.

As I was having the odd brake squeak I also stripped the pads and cleaned the caliper/pad interfaces and re-lubed with brake lube. Also removed the stuck slide pins that were gummed up, cleaned and lubed.

Wheel alignment tomorrow.

Feedback on this thread, i managed to get my Disco out on to a quiet road and did several (maybe 8?) hard stops from 110 to 20kph in succession and has completely cured the brake shudder. Very happy. Interesting side point is after 4 or so stops there was some pretty good brake fade - obviously pushing Disco well outside design envelope. Brakes returned fine once cooled.

That's interesting. My indy has my 2016 SE at the moment, looking at a nasty noise coming from left front suspension on full right hand lock, but at the same time I've asked him to check noticeable vibration under brakes from high speed. New rotors and pads last year and new LCAs a few months ago, so unlikely to be that. Will do the high speed multiple stops when I get it back and see if that makes a difference.

[wardy1]

Really interesting thread. Recently had new rotors and pads on the rear and pads in the front. I really had no issues but decided to try this ‘rebedding’ as an experiment. The difference in a car that has always had fantastic brakes is very noticeable. Thanks for the running the thread

Hi DiscoJeffster

Understand that the HD version is stronger, would this make the ride feel stiffer compared with hydrabush?
Thanks

I’ve not noticed any difference

[haydent]

did you work this out i have this problem too (L320), have replaced LCA and now new tyres with alignment... ?

ive tried checking the discs for warp, seems good,

only 108k km on clock, thinking to try a shop.

[josh.huber]

I've got akebono ceremics pads, I find that they develop a shudder and need the brakes to be stood on aggressively to stop it.
The biggest shudder eliminator was the rear control Arm bushes on mine. Very different mileage but, mine had about 270k when I did it.

Tried that too Josh after replacing all control arms, sway bar links, struts, bearings, wheel balance and full alignment. Only thing left was to skim the rotors, all better now.

[haydent]

rotors where high on my list too, (tried the hard braking bp too) i will focus on them next thanks
