yea, the taper was supposed to deal with lateral loading better... in theory.

It could be the inherent design of the bearing hub is the problem, or these are junk. I can't assess which and it would be unfair to cast blame without further empirical evidence. A lot of folks are still running on these units and this is the first failure; a track failure at that.

I would have to call it an aberration unless more start to fail all at the same time.

I just got a pair of Tommy Morrison surplus rear bearings with Mobil 1 synthetic grease in them. The M1 grease is supposed to help them live longer by not breaking down into waxes and losing lubrication ability. For $100 each I will give it a shot.
