R1250 RS drive shaft replacement under warranty

[Mark]

Not really sure why our drive shafts, that used to be good for 70k miles are now only good for 12k.  But it does make me a bit nervous.  My 2017 red frame now is at 47,400 miles.  Just did a road trip to Jackman Maine and now need to start thinking about Trempealeau.  So today I pulled the shaft and changed the rear drive oil.  Shaft looks and feels like new, so I lubed the splines with moly and put it back together.  Pretty sure the red frame is providing protection to the whole final drive system.

Greetings Bob, 
I think the drive shaft is inspected/tested every 12,000mi and replaced at 36,000mi. The U-joints are
the weak link in the system
