I replaced the rear wheel bearing and seals yesterday. Actually, it wasn't too bad of a job. I read the FAQS on the job (Rear Axle and Wheel Bearings: Wheel Bearing Oil Seal) and the writeup had two points that could be clarified:
The sealing ring is very hard to pull off with a puller. A mechanic friend showed me an easy way. He had a cold chisel and a maybe 3 or 4 pound hammer. He just put the chisel on the sealing ring and rapped the chisel a few times and the sealing ring split and came right off. The bearing then came off easily with a press and split halves bearing removal tool.
The old inner seal was not pressed in all the way so I assume it went in with the complete half shaft. The splines go into place before the inner seal meets it's housing. This makes a cylindrical drift unnecessary. I did, however, remove the half shaft after pushing it in and seating the inner seal, bearing and outer seal to see how far the inner seal went in. It felt like it was in the same position as the old seal. The old seal had worn a small ridge on the shaft so I did use a cylindrical drift (pipe fitting) to push it in further a very small amount so that the inner seal would be on a fresh part of the shaft.
