I started to tear down the rear drive unit. The seals are shot, so the whole thing should be taken apart and inspected before I put new seals in. The U-joint gave some trouble in removing it from the flange. I had to drench it in penetrating oil for a few days before it would come apart, and even then it took quite a bit of persuasion with a putty knife and hammer.
The brake shoes gave me a little grief in the removal process, so I ended up making a tool to remove the shoes without getting any fingers pinched, etc. I don't know how I functioned without a MIG welder in the past.
