Well my final drive has gone for the second time. 
It's an '04 1200GS, well out of warranty with 42k on the clock.
The solution found here will determine if I get rid of BMWs for good and go back to Jap bikes. I don't want to as I really enjoy riding mine. But if I cannot rely on the bike then it doesn't fulfill the brief for me. No point taking my BMW touring only for a part to fail that I cannot fix, (just back from 2800 + miles around France, Spain & Portugal).
What are the options and costs of final drive replacement?
Mine has bearing play and the outer seal on the left has just started weeping.
Can they be rebuilt yet, is anyone offering that service and how much?
Or, is the only option complete replacement of the unit? Again, how much & is it dealer or breakers only?
Which is what I had the first time by the dealer as they said it was more cost effective and they didn't have the tooling.

. The bike is way out of warranty and the bearings in the FD don't last forever. Things do wear out you know......!

If it does happen (and I sincerely hope it doesn't) you may change your mind.
