Transverse & Rear Trailing Arm Bushes 156 ?


having replaced my rear tyres due to inner worn edges i have come to the conclusion it is down to either one of these suspension components, i might sound dumb but the trailing arm is the curved arm which connects down to the rear hub ?, and the transverse arms are the straight ones with 4 of these altogether, now im only looking to replace the bushes on the curved rear arm and to replace one of the transverse arms which is currently bent slighty.

are genuine bushes recommended or will pattern parts fit ok ? and just to make sure it is the rear arm knocking the tracking out at the back ?

i did have a read about on the forum, but no harm in asking

You've got the idea....if one of the transverse arms is bent, that will affect the rear wheel tracking, and very likely cause tyre wear........effectively if one of the rear arms is bent the wheel will toe out, and if one of the front ones is bent, it'll toe in.....

I'm not sure if any of these arms can be re-bushed, but they aren't very robust so I'd recommend replacing the complete arm if one is suspect.

If you're interested I have two more sets of the custom made rear arms made out of high grade seamless steel tubes and PU bushes.

Here is the thread where we've discussed all the details. (Rear transverse arms - UPGRADE)

Ive never needed to do it but shortly an expert may add that these arms are adjustable as the front and rear tracking can be altered.

There is only one bush on the trailing arm (curved rear arm). Its at the body end and rarely wears out. This is probably not the source of your trouble. There is a bush pressed into the bottom of the hub that the trailing arm bolts onto. These wear and need replacement from time to time. These bushes are super cheap.

Of the transverse arms, 95% of the time only the bushes in the rear bars wear.

So 2 x new rear-most transverse arms and 2 x replacement hub bushes, plus a proper 4 wheel alignment will probably sort out your tyre wear issue.
