I know some time ago Kenny did a write up about repacking the wheel bearings. I will be doing this since I have to take everything apart to replace the rotor anyways. My question though is do I NEED to replace the seals also? Advance Auto is the closest auto parts store and they do not carry the hub seal. If I must replace it is there a place online I could order them from? I searched the part numbers he listed in his guide but did not find them.
