U Joints 92 300D
 

I did a search and did not find much.
I believe my u-joint is going bad on the drive shaft. It appears Mercedes, or Fast Lane does not carry them. Has anybody ever replaced one of these? I know my front flex disk is bad, but when I grab the front shaft, and the rear shaft and twist, I get about .030" play. I have not confirmed if it is in the spline or joint, but from my experience, it feels like it is in the joint. I can buy the whole rear shaft with joint for $500.00, but if I can get the joint , they are typically no more than $18.00, go figure:( .

The drive shafts on these cars (incl the ujoint) are quite robust. Generally, it is the support bearing or the support bearing mount that has problems.

I have replaced a number of support bearings and housings on my 190 through 370,000. The u-joint at 370,000 has very little play.

I don't think you searched hard enough. There's lost of discussion about driveshafts here. Try here.

Thanks Rick and Jobah.

I am probably going to have to pull it down and carefully exaimine it. I know the flex disc is bad, but not sure about the u-joint. When you grab the drive shaft and turn it back and forth, I get a clicking sound out of it, but it could be slop in the spline of the split shaft. Is that common?
