Just a followup. Jim's Drive Train Specialties finished the repair on my truck on two days ago.
Jim's crew installed a Dana 80 differential overhaul kit which included axle shaft bearings, pinion bearing and pinion seal. He said that visually the ring and pinion gear looked to be in very good condition. However, after setting up the gears and checking the pattern, he said the pattern was where in should be, but there was some wear on the ring gear. He said that it would not be a problem, but it will be noisy - just not as noisy as it was before the repair. It turned out not to be noisy at all - quiet under all operating speeds on the 150 mile trip home.
I am very pleased with the service from Jim's Drive Train Specialties. If anyone is needing drive train or axle work done in the Boise, Idaho area, I highly recommend these folks.
