The hub came off without a problem, but how do you remove the seal at the back of the hub? That thing is really stuck in there. The metal is fairly substantial and certainly does not look like a screw driver could fit between it and the hub. It looks like it needs a special tool to yank it out of there. Do you pound it out from the inside? I'm afraid to do that without hitting the rear bearing. Lastly, there is quite a bit of grease in the inside chamber between the front and rear bearings. Any reason why its there and should it be removed and replaced with new bearing grease? Thanks again for your help.
