Thanks John,
I have a B200 CDI automatic... 2010 model .. I have noticed a strange clunk noise with a slight jumpy type movement when reversing on full lock (both sides).. its hard to explain .. but to me it feels like the tyre is trying to come off the wheel rim ??
It's fine on full lock going forward ?
I know CV joints "click" when they are worn .. this is not like that ...
Any Ideas what could be causing this ?
Andy...

If its only on R, have you checked gbox or engine mounts.
Too much guessing gets expensive. Where are you located, have you a good Indy nearby.

Hello and welcome.
My SL55 does this, and I suspect it is the top arms. Just a wild guess

Hello mioba,
It's only in reverse on either Left or Right full lock ? By Indy do you mean independent garage ?
Thanks

Hello 00, you say you had this problem.. what are the top arms ? Part of the suspension ? Have you had yours fixed ?

They are part of the suspension mounted to the body and attached to the hub uprights, they have 2 bushes and a ball joint. If there's wear they can move and make the wheels jump when on full lock and you're moving forward or reversing.
No I haven't done mine yet.
