It's an easy one Bim... about a five beer job, at most. Get some rubber gloves for the packing festivities. I usually just chuck the old bearing altogether... like a water pump... if I'm in that deep, I'm not putting old stuff back in. They are cheap enough, well under a hundred bucks if I remember( I pulled the OEM's at like 5000mi. and found them rusty! I was only repacking with Mobil one, and ended up chucking them) I'm anal as hell that way. I always replace wear items at service time, whenever feasible. Wayne
