Here is an eaiser way to get the rear seal off the hub.

After removing the nut washer, and outside bearing, install the nut and turn it 3-4 turns. Next pull the hub aginst the nut, this will grab the inner bearing and hold it and the seal on the axle while the hub pulls off the axle. This is helpfull if you want to reuse the inner axle seal, as it usaly dose not damage the seal. Old mechanic trick.
