MB designed the drive shaft & then found under "some" conditions that there was TOO much vibration, so they added a vibration damper. IF possible always put back the same "stuff" that comes off.
THERE are 2 sizes of this damper for the 2 different sized flex discs that they bolt to.
The PART NUMBERS ARE 202-410-05-47 & 202-410-11-47.
The list price is around $125.
I don't have one on my racecar anymore.
