Are the drive shaft carrier bearings replaceable (not the mount bushings)?
My drive shaft seems to have "excessive" movement when I push on the shaft from underneath the car. If they are replaceable are there aftermarket urethane replacements? I am having a tough time finding anything on these. I am guessing they are not replaceable because of this.

I dont believe they are rebuildable.. Here is an option if your driveshaft seems to be sloppy..

Mike,

Sorry I just saw your reply. I know this goes back a little while but they are rebuildable. I put new bearings in mine. I used a bearing splitter to get everything apart after marking the full shaft for balance.

Part Numbers are:
MR553202 (Rear Section)
MR553201 (Front Section)

If I had the money, I would have definitely considered going with your aluminum rear section
