Anyone have this problem yet to know how common it is?

Swing bearing at middle of drive shaft failed this weekend on my buddies 900 trail. Sealed bearing seized causing the rubber mount to be pushed forward out of the holder, nearly off the rear splines, and banging the frame as the shaft spun. Replacement part number showed an update by polaris. Picked up part and repaired on trailer, then back on the trail.

Just wondering since so many 900 trails have been sold and we have several that ride with us.
