I own two 83 Benz and it is amazing how similar they are so I thought I would share this experience. My 300D had vibration at about 45 MPH. I did everything to fix the problem but nothing changed until I replaced the drive shaft center drive shaft support. The fix resulted in vibration from 45 to 60 mph so I thought one of the problems could be that the drive shaft was out of balance. I checked the Internet and found many references to balancing a drive shaft using a simple worm screw hose clamp. I gave it a try....for a $1.79 and an hours time investment there is now absolutely no vibration at any speed up to 70mph.....and I feel certain beyond. I don't recall a specific link or forum but the hose clamp works and the info is easy to find with a Google search. I left the clamp loose enough to move it around until I found the right balance and then tightened it down tight. I am so happy I could just.............
