I did a search and came across a thread that t. walgamuth responded to and said to put the car in neutral and try and wiggle the half-shaft, if you can wiggle it then its bad. I did this, and there is no lateral movement, it only slides in and out about an inch or so. Any help would be greatly appreciated.

Bryan,
Tell us when the sound occurs: up-shifting, down-shifting, over bumps, in reverse, always, sometimes? More info is needed.
regards,
Mark

About 5 months ago it started making a lower pitch clunking noise in the rear end, mostly during heavy acceleration and turning. When I took it to my mechanic the next day the noise stopped therefore the mechanic wasn't able to hear the noise. Just recently there is a higher pitched clicking noise that occurs after the car reaches 20 to 30 mph and is constant with normal driving. I also tried the car in neutral and coasting and the car still made the noise. The noise also gets louder the faster I go. I don't know if I stated in my post, but it is a 1993 300E. Sorry for the blotched information. Thanks for responding.
