My car has been making a clunking noise from the rear at low speeds. I just got off the phone with a local shop that I've never used before, but the guy knows the car (my old guy retired). He says it's probably the bushings. He's done the job before. He says that there's an upgrade kit from Mercedes made for the 300E that he recommends installing on a 16V because if you put the OE bushings on they will just wear out again.

Anybody know anything about this problem and/or the upgrade? Anybody ever done this job?
