Well rear wheels bearings are done. Really not a bad job to do. There worst part was having to crack open the rear end and re-seal when I was done.
The truck runs SO smooth in the seat now!
Thanks for your help dj and everyone else.

The axle did have some pitting where the trashed bearing road. I cleaned up the high points with fine emery paper. The new bearing kits I bought are basically a sleeve with the seals and bearings built in. This setup moved the bearing outboard just enough that it is ridding on a fresh axle surface.
The new bearings are packed with grease as the oil seal is inboard from the bearing. There is an outer grease seal as well. These may not be as good as what is in the truck from the factory, but it beats buying new axles for now. Hopefully packed grease bearings hold up like the oil-lubricated ones do.... We'll see!
Here is an example of the wheel bearings I went with:
A note on the part numbers:
Timken shows TRP1563TAV for the 7.5 and TRP1559TV for the 8.8. I learned the hard way that the TRP1559TV is ONLY for the 31 spline Level II or Explorer 8.8. The majority of us need the TRP1563TAV for all 28 spline rear ends. This includes 8.8 and 7.5. It appears that regular Timken rear bearings have the same issue. I am not 100% on that, however.
