The seal you are referring to installs inside the axle housing at almost the end of the axle shaft, just inboard of where the hub fits on. Tom Endy's article contains a lot of information you may find useful. Also, if you do not already have a copy of Les Andrews Red Book, do yourself a favor and get one! There is excellent information on rebuilding the differential in it, including expanded drawings.

A-4221 is the differential bearing that installs on the ring gear case, not the seal. The seal is A-4245. You can simplify your life if you use A-4246 (Snyders number) to install it. It uses pipe with 1/2" NPT threading, which may be a bit problemmatic to obtain in Germany. Check for wear on the axles where the seal rides.
