This weekend I disassembled the rear differential on the GMC.

The diff only had about 2 cups of fluid in it. Sounds like it had a leak at some point. While I have it apart I am going to sand blast the case and paint it. I will also replace all the bearings and seals, and finally put some fluid in it.

I also got the remaining control arms installed on the front. Had I had a coil spring compressor, I would have also installed the coil springs and the spindles. That will have to wait til next weekend.
