I suspect a lot of bearing problems are caused by incorrect refitting of the propshaft. I believe (please correct me if I'm wrong) the bearings should be perfectly at 90deg to the VCU shaft. There is a lot of movement in the mounts and it would be easy to mount them so that the rubber is always flexed therefore under strain shortening the life of the bearing.
Also the front half of the propshaft is at an angle and some people may try to straighten it by flexing the rubber mounts when the angle should be at the universal joint.

Spot on Alibro. The bearings should be at 90° to the VCU, not in line with the propshafts, which aren't in a straight line between the IRD and rear diff.
