rear wheel seal
So over the course of the last year I have replaced the driver side rear wheel seal 3 times and its leaking again. Sometimes it makes it a few months and this last time was a few weeks and I dont drive it daily. I also replaced the bearing the last time too. I know that this means most likely something else is to blame but I dont know what. I looked at the axle and it looks straight and smooth but that doesnt mean it is. I have used a couple different aftermarket seals and maybe I will try the factory one. The worst part is with the G80 I have to access the rear diff to remove the axle which means a new diff seal and fluid too. Any one have a similar issue or possible reason. I dont hot rod the truck and it doesnt get offroad as often as I would like.David

Do you know if it is leaking at the seal and axle or the seal and housing?2000 GMC YUKON SLT, 5.3L tow pkg, G80 rear/w 3.73 gear

Im not quite sure. Ive tried looking before and wasnt sure, but will look closer. The surface of the housing looks good. There is a small nick at the edge of the housing that had a little edge. I tried smoothing it a little bit but the seal seemed to extend past. I will check the seal when I pull it to see if it dented or creased the seal when installed. It could be my memory playing tricks but I dont think it seemed like a tight seal between the rubber and axle last time.

No shame in that. Nice picture. Is that rust and pitting that I see on the axle and is that axle part way out of your own doing? I ask because of the fairly shiny surface out past the seal lip seams to be alot of play in it if not. If that is indeed pitting and rust at the seal lip, then the seal is not your problem it is the axle surface where the seal rides.

Thats kind of what I figured
That "C" clip is also in the non-locking axle.
Maybe if not too deep, it may need to be turned on a lathe

I take that back. the only ones I can find right now are for full floating axles
