Hey gang,

Last week we sold my wife's 300D. She's been driving my 240. Today she e-mailed me at work and said the car was dead.

This morning there was a hard 'clunk' when she put it in reverse. It also 'clunked' and shook when shifting from 1st to 2nd. She did not drive far (1-2 miles), and said it was worse on the drive home. She also said there was a pink, 'milk-shake' looking puddle under the engine before she started home.

I had her check the fluid level and it is just below the top dot on the dip-stick and there is nothing in the driveway now. I had her drive to the end of the street and back. She said the car was shaking like the wheels were about to come off! I had her check the wheels... bearings are tight and lug bolts are secure.

Does anyone have any idea what I should expect when I get home? Suggestions? Where should I start looking? Transmission problem? Or Rear-end? I am at a total loss... maybe because I am not home with the car...

Thanks for any suggestions,

First things that come to my mind, are flex discs and driveshaft center support bearing. See what you can see under there. Good Luck

Larry,
I believe you are right. I checked the entire front end and found nothing. I checked the tranny and it seems fine; fluid is perfect.

I drove the car again last night and the shake was horrible, but no grinding or 'failed parts' noise. I have always tested drive-shaft problems by trying the car in different gears to see if the shake is always at the same road-speed or RPM. The shake on this car starts before getting to 10mph, so regardless of gear I try, the tranny is always still in first before the shake starts.... it also shakes in reverse, but not as bad.

Tomorrow is the start of my weekend, and I am going to climb under and start exploratory surgery. My money is on the center support bearing! At least I hope so, because I have one in the garage. It has been making noise for the past few months, but I have been too lazy to replace it. I guess I am 'paying' for not keeping up with the maintenance like I should :(

I'll let you know what I find.
