Suppose you're asking about replacing the outer rear bearings/seals? If so here's a real good thread w/pics on how to do it for a 44a and the 35C is exactly the same w/same part numbers. Get a loaner slide-slide hammer bearing/seal puller at your local auto parts store if you don't already have one. Good luck.
YW, good luck, and thanks to Polka Power for passing that link into a thread I started when doing mine!
If you have both rear axles off the ground just don't turn the axle shaft with the c-clips, pin, and one of the shafts removed or the gears/thrush washers may fall into your pan of gear oil! Don't ask me how I know...
I'm sure you already read the link posted above, but here's my method:
1. Removing old seal just work around the outer edge of seal bending in the edge with a flathead screwdriver and a small hammer, it'll pop off fairly quickly. Make sure not to gouge the axle tube.
2. For pressing out the old bearing, I've cut a piece of 1/4" plate that fits through the bearing and snuggly sits on the outer lip of the bearing. I've welded a nut on the plate, then use a long enough bolt and something against the end of axle tube to drive off the bearing. Can also be done using a slide hammer but IMO this is easier..
3. To press in new bearing and seal, I use this method. I use the old bearing on top of the old one to protect it when pressing in. Do not press in the new bearing from the inner ring, only on the outer.
