Has anyone got any idea how to get the drive shaft and final drive separated it is welded it with rust Id advise anyone who buys a new GS to grease these parts so you don't have any problems in the future .Ive tried WD40 and trying to tap it off with a mallet but no joy cant use heat because of all the seals in there IF BMW WOULD JUST SPEND A FEW QUID ON GREASE AT FACTORY or indeed make it part of the service schedule all would be fine many thanks
