Snowblower driveline disconnection during Operation

[Luis Borges]

I have a BX2370 with BX5450 snow Blower. The rear driveline disconnected from Output Shaft during operation and broke the U-joints at the rear of the driveline shaft. The Output Shaft appears to have moved forward causing the female end of the driveline to disconnect. Ideas why this may have happened?

There is 2 bearings with stops that hold that shaft, check those.

Thanks, that was the problem. Apparently Kubota switched the bearings such that the setscrews were directly in the bearing rather that having an attached shoulder. In my opinion, a very dangerous change.
