W211, common rear suspension faults please.

If any body does find the answer to the original question I wouldn't mind a bit of info my merc tends to rock to the side when it changes up gear now and again any help would be appreciated

This sounds sub frame mounts at the front

if the mount at the back of the gearbox has worn that would cause some movement when changing gear
Its an easy job and costs about £35

Very busy at work but eventually had time to check the car and rear suspension, O/S/R shock absorber was gone. Totally open circuit/flopping about.
Cheapest place was Mercedes compared to Euro. The new one is modified/different without the little cylinder attached at the bottom.
Very easy job to do.
