I did the shaft spline re-grease on my 1250 (front and rear) with Rocol moly paste, both splines had a tiny residue of what looked like Starburags, resealed the gaiter with Starburags, drilled and tapped a drain hole in the lower cup section of the swing arm (that can hold water if any gets in in through over zealous power washing) as the guy called SAFICOM on the You Tube video entitled.....
'BMW R1250 R1200 driveshaft rust fix'.
Have a look on You Tube, maybe someone knows how to put a link on here for the benefit of others, mine has been fine since, I will probably look at at again over the winter months.
