My 1987 300SL suffers from shake or wobble that can be felt through the whole car ie. not just through the steering. The shake isn't present all the time and if the road surface is smooth its hardly noticeable at all. It seems to be initiated by driving over pot holes or rough surfaces whereafter the car 'oscillates' for a couple of cycles before settling down again.
Lots has been replaced at the front end - tie-rods, steering damper, idle arm bushings, shocks (all round Bilsteins) etc. and Mercedes have recently carried out a 4 wheel alignment. The engine mounts have also been cahnged most recently. The car handles better than it did but the wobble is still evident.
I see there are what look like dampers (2) next to the engine mounts connecting the engine to the chassis. These have not been replaced. Before spending any more time and effort on this problem can anyone give me some guidance on this problem and what the purpose of these dampers is and whether these could be significant.

Thanks

Have you had the sub frame mounts replaced? This is a 107 body 300sl correct?

Yes. The sub frame mountings have been replaced twice - the second time because MB told me they had too much play after a non- MB place changed them previously.

If your tires and/or wheels may be out-of-round. Sometime even new tires are out-of-round. It happened to me twice and the effect was similar to your discription. Good Luck.
