Something does not seem right.

10K miles is way to soon for the damper to give. It may be worth while to pay and have a MB dealership do a diagnostic test. Ur problem could be else where.

Just a shot - what is the condition of ur motor mounts and tranny mount ?

When I got my used 93 300D, there was a hell of alot of vibration. I replaced the motor mount and the tranny mount. Still not much change. Finally diagnosed it to a wrong exhaust on the car. Had to have the exhaust cut and shorten and the vibration went away.

My guess is u may may have something else causing the problem. Replacing the damper will not solve the problem.

I would look at the engine running, from all angles and see if there is anything that catches ur attention.

It may be worthwhile to have the stealership look at it. Pay them to diagnose and u can do the job urself.

My 2 cents.
