Re: reasons for pivot bearing failure?
If you mean the two that connect it to the swing arm, it is because a tapered needle roller bearing just does not work well in this application. They develop notchiness as they beat aganst the races with little rotational movement. I replaced mine with Rubber Chicken Racings solid oiltite version bearings. If you do use them, you reduce the preload on the them to about 1/2 what the needle bearings call for.
If you mean the taper bearing on the hub unit - it was taken out by the creeping race on the pinion shaft. This is based on the pictures you had submitted earlier.
