Drive Shaft seized on the final drive splines

[Grumpy Goat]

If you look at a parts fiche for the R1200RS you will see there is a snap ring "holding" the shaft in place on both the part of the shaft that is closest to the trans and the part of the shaft closest to the rear end.

The above had me go and check since my Haynes manual makes no mention of a rear snap ring, only one at the gearbox end. Looks like there is only one we have to worry about. That must mean that it is rust at that rear end is giving Michael grief.
