Default Uneven Rear Tyre Wear

Hi

Can anybody tell me exactly which bushes i need to change on my 2004 75 CDTI to eliminate the horrendous uneven rear tyre wear??

I have a twitch at the rear when going over uneven ground/poor road surfaces so assuming this is part of the same problem.

I will get geometry checked after work is completed providing the bolts can be undone

Thanks
Col

I would also be very interested in any suggestions. My tourer eats rear tyres every 4-5 months (but just on the outside - was told "they all do that" by someone) along with a constant knocking that we have yet to locate. Good luck with yours.

Have you checked the rear arms for rusting. There are bushings in the rear arms and the trailing arms.

In my case, all arms and sub-frame were replaced with new, only the large bush within the front of the trailing arm wasnt changed. Could a worn one lead to excessive tyre wear (and account for my constant knocking)?

If the rubber bushes are worn, yes. Jack up and test for movement with a long pry bar. The only movement should be minimal give in the rubber.

When And If you get the track checked, make sure they adjust the rear axle first. Don’t let them touch the front tracking until they have done the rear.

I have been driving 75s since the saloon launch night and usually get between 18 and 30k out of a set of rear tyres depending on quality and how hard the car is driven.
When I have had to rebush the rear I have always fitted polybush sometimes it is cheaper to fit them than original bushes. To date I have never had to replace a poly bush once fitted and some were on the car for over 300k of hard driving.
I am in the habit of running winter tyres November to April and Summer ones April to October. Though the last couple of winters I would have got away with summers all year round.
Hope this helps
Alan
