I was in the process of removing the rear drive so I could grease the splines on my 1985 K100RT. As I removed the drive assembly, the drive shaft came with it. The shaft was a little stuck on the rear drive splines but with a small tap of a rubber hammer the shaft came right off. I cleaned the drive and shaft splines and they look nice on both ends. It only has 30,000 miles but does not appear to have ever been lubed previously. The problem is the u joint is a little notchy when moved up and down, either direction, so I would like to replace the u joint. I looked in my Haynes and Clymer manuals but neither has any info on u joint replacement. I looked on a couple of the BMW web sites for parts and don't see the u joint listed as an available part, only the drive shaft assembly. In searching the K100 forum I did find one topic on this saying the u joint is replaceable, but does not have C clips holding it in like is typical with cars. Rather, t
he u joint is staked in. I guess my question is has any one replaced their u joint and where do I get parts. Thanks,
Jim
