How to Replace Toyota Pinion Oil Seal in Rear Differential/3rd Member

Today I replace the leaking pinion oil seal on the rear diff of my 1985 Toyota Pickup 4wd. I replace the seal without replacing the pinion crush sleeve and having to reset all the preloads, requiring complete disassembly of the 3rd member. If you're interested in the full disassembly and re-assembly of the rear differential, I uploaded scans of the factory service manual here:
