The Project Pad

I'm wanting to replace the rear diff seals and wanted to see if anyone had done this before or had any tips for doing it. I don't want to stick a leaky/oily rear diff under the car after replacing and painting everything. Do I run the risk of having to set up backlash or something that might get me in a bind?

The output flanges are held in by a dinky 8mm bolt and just slide out of the splines on the side at least. No adjustment required, the seals are pretty easy to replace.

Thanks. I think I'll give it a shot. I was looking at the Bentley and it was calling out a special threaded rod/tool
