**UPDATE**
CPP has done right by me. They are shipping me a new set of bearings and miscelaneous parts. I had a long phone conversation with one of the reps following up. Apparantly I am the only one that has had problems with the bearings.
I do use my truck as a daily driver and a work truck. Perhaps the bearings are not up to the task of carrying loads. Perhaps I got the only bad set of bearings. Anyway the replacement bearings from CPP will not be going on the 59 1/2ton. I will instead use them on my 1940 project.
