I had the same problem on my 86 300E. It turned out that there was a dampener of sorts on the transmission end of the drive shaft. That thing consisted of a rubber coupled steel ring assembly mounted on the end of the drive shaft. Well needless to say the old rubber gave way causing the shaft to be out of balance. That caused high vibration forces which over time ruined the drive shaft coupling where it stabs into the alignment pin in the back of the transmission. I ended up replacing the drive shaft to solve the problem and I was not able to replace the dampener since BM did not sell that thing separately.
