Yep, I put it back to the factory marks and I checked it before I pulled it to make sure it was there to begin with. It took a lot of force to remove the centering bushing from the front shaft(the part that centers the shaft to the transmission). I replaced front and rear centering bushings as well as both flex discs. I didn't lose any weights. One thing I have thought of: The support bearing's rubber mount was sagging slightly, the new one raised the shaft a little. The u-joint had a spot that it was riding in that for a while and it seems to stick there when you rotated the joint by hand. Maybe I've gone out of that area now that the rubber mount is new. Whatever, it's pissing me off, I've done driveshaft support bearings on everything from Chevy S-10's to school buses and box trucks and I've never had this problem.
