Got the dreaded news today from the BMW shop, metal shavings when they drained the final drive oil on my 2003 K1200 RS (52K miles). I realize this is a common problem, so I was surprised a search on this forum didn't turn up many recent discussions of replacement options. Beemer Boneyard is sold out, eBay has one for $150 with 71K miles which seems like a potential short-term solution. The shop told me they could tear it apart to see what parts need replaced, but once they go down that route I would not be able to trailer it home and that's another 2 hours labor, that doesn't seem like a good approach - or is it? Maybe the parts are minimal and reasonably priced? Or, is the best option to look for a used final drive? If so, do you have any suggestion on sources? Thanks in advance.
