W211 baffling suspension noise

[jonviola]

Hi

My 53 plate E320 cdi est makes a weird clicking/popping sound from the front suspension. It only happens when you turn the steering wheel not in a straight line.

Ive checked all the ball joints all are fine but changed one ARB link. This hasn't made any difference.

Does anyone have any suggestions? I'm stumped!!

Wheel bearings?

Loose wheel arch liner rubbing on the tyre?

Thanks I'll have a look.

Could it be shocks? Springs?

Nothing obvious to the eye...

Found it!!! Couple of worn rack bushes...

Cheers
