MB Paul :

Hi, My name is Paul & I will try to assist you.

MB Paul :

If you are 100% sure that the brake discs are ok then I would be checking both lower arm ball joints & bushes for wear & movement

MB Paul :

Worn shock absorbers are also a possibility

MB Paul :

By far the biggest problem we see is with the brake discs & it may not be that obvious on initial inspection - check for any pad shadows on both faces of the disc & inspect with a DTI for runout on both faces of the disc.

MB Paul :

We replace many discs for this problem so unless you have already fitted new discs I would not rule the discs out at this stage

MB Paul :

Best regards, Paul

Customer :

I have replaced discs

MB Paul :

ok - as said I would next look at the lower suspension arm joints & bushes

MB Paul :

the joints can wear giving excess movement & the bushes are prone to splitting or separating - give them a good lever with a pry bar to check

Customer :

thanks for your reply will check all joints

MB Paul :

no problem, let me know how you get on

MB Paul :

best regards, Paul
