Live axle steering wobble, they say it's tyres

**newhue** · 13th March 2012, 07:46 PM

from new my Defender 130 has been wheel aligned and balanced every 10K

From new at 95 to 100klm it has had a small to medium? vibrating shudder through the steering wheel. LRA said it was with in tolerances, and still did it after they did another alignment.
So I had an alignment at my local goodyear and fix the issue.
From new I have run the tyres using the 3psi rule.

My problem is that every 10K when I rotate the backs to the front I get a nasty pulling to the left, and the shudder comes back so that's why the trip to goodyear every 10K. I don't cross axel rotation as having 6 tyres, the fronts go in the shed and the shed tyres go on the back.

Now my XZL's are about half worn, maybe a bit more, any they shudder more than ever. Not always, but on most smooth surfaces.
Goodyear say it a common problem with mud tyres that are half worn, and live axels. Furthermore they say don't be surprised if this coms back after the new set is half warn.

Has anyone experienced this?

My apparent fixes are
drive at 90klm
get new tyres and see
find out if something is a miss with my front end.

thoughts please

thanks

Can't help I'm afraid, but I have wheel shake too and a set of half worn bfg's (made by Goodyear I believe).

Doesn't make a difference for me though if the 2 most warn are on the front or back.

it weird, but I accept it will pull to the left due to it's caster and make. I accept the left front gets much more wear due to this, just frustrating it doesn't drive at 100 like it does at 90klm.

in no particular order

check the balance of the tyres
check the roundness of the tyres (feathering, scolloping)
check the wheel bearings
check the swivel pins
check the mounting of the steering box
check the panhard rod bushes.

IF its none of that

you'll probably find that its a road hammer balance issue. and thats a proper pain to sort out.

The only "wheel alignment" that can be done is adjust Toe in or out, there is no other adjustment, it is set. How much have they been charging you for a "wheel alignment",
camber and castor can only be "set" using off set radius bushes or slotting the bolt holes where the hub assembly bolts onto the diff.
As Dave says could be tyres out of shape, check for any bumps, take off and roll along some flat concrete and watch for egg shape motion, Regards Frank.

How old is the steering damper ?

I don't see it mentioned anywhere else in the thread but a replacement of that fixed a very similar issue one mine

haha, Fair enough

I had what appeared to be an original damper which I assumed would be pretty flogged out after 200k km felt made a fair bit of difference.

That said re-reading the post it sounds like a fairly new 130 so it shouldn't be that anyway
