Is there some trick or magic to replace the rear axle bearings?

[smoedog]

21 1500 Rebel, 3.92 e-locker...A few months ago my pinion bearing started going out and making noise. Took it to a highly recommended off road shop to get the rear-end rebuilt. I told them since they were that deep in there to go ahead and replace the axle bearings and seals while they were at it. A few weeks after they were done, the passenger side axle seal started to leak. I stated to get into it and found the axle seal was pushed out and the bearing was shot. I could lift the axle up by almost half an inch in the housing.

Took it back to the shop and they said the out race failed and the bearings ate into it. He told me he called his supplier and they think it was a heat treating issue. They threw a new bearing and seal in it and he was going to work with the supplier. So I have had the truck back for 2 months and now the drivers side bearing just failed exactly like the passenger.

So I am wondering is there some unknown steps or something special when replacing these bearings, or maybe the wrong bearings put in, or this shop just screwed up.

Im at a loss.

Should be a straight forward procedure. Did they use non OEM parts perhaps?

They used Precision Wheel Bearings from the box store. I had to use the same bearing they used to get back on the road. We will see if it lasts...if not i'll get some oem. Only thing I can think is either a bad batch of bearings, or since they rebuilt the entire rear axle, they drained all the fluid out but didn't add any oil to the bearing and tubes and they were dry when I picked it up.
