Dennis, I hope all goes well for you! When my bike started to wallow in the rear a little, I thought I had a flat. Then BAM! all hell broke loose. It was very tense for the next few seconds.
BMW seemed reluctant to warranty this at first simply because they had never seen this type of failure before.
Luckily I have a very good dealer!
I hope BMW N.A. see's this thread so they know I really wasn't full of shit
My bike had 7000 miles on the clock when this happened
What was your mileage when your bearing failed?
All the best
