1983 Mercedes 240d Shakes like a massage chair
 

I have recently picked up a 1983 Mercedes 240d w123. I have been going through the basics and can't seem to improve or slow down a crazy vibration problem. I have replaced all 3 motor mounts, trans mount, adjusted the valves and have replaced all 4 fuel injectors(injectors were leaking). Nothing has seemed to make any type of improvement. My question is, is there a certain procedure for installing new mounts on this car? I have seen many posts that ask if they were installed with the car lifted in the air or sitting on the ground, does it make a difference? I would also like some advise on the type of mounts that should be purchased if the OEM are not available. Any help would be greatly appreciated.

Give up the dope. When does it vibrate?

Change your rack damper bolt

Unfortunately 240Ds don't have a rack damper bolt.
