Rear pinion seal 97 Jeep Grand Cherokee Laredo

Ok guys looking for a little input/ advice. Had some work done 4 months ago at a shop. Work that I could not do myself, seeing it was there even though I could do this one I had them do the rear pinion seal because it was leaking. 4 months later it is leaking again. I bought a new seal yesterday and put it in. Took it for a test spin and the new seal leaks worse then the one I replaced. I made sure it was put in square and everything else. Any thoughts would be great.

I bought National brand seals for mine, haven't made the repair yet. There are some good guys here I'm sure can help. I'm interested myself on input. Good luck.

I've seen the pinion yoke develop a groove right where the seal rides, so even a new seal leaks. I don't know if anyone makes a sleeve for the pinion like they do for a crankshaft, also, coat the seal lip in synthetic grease before you install the seal, that way the seal does not have to ride on a dry piece of steel, and allows the yoke to slide cleanly through it when you re-install it.

Retreat? Hell, we just got here......

Thanks for the input I believe that may be my problem as you can see from the picture I uploaded you can see the grooves. looks like a 46 dollar part for a new yoke which I guess isn't bad at all. any other theories from anybody just in case would be great

it looks like pitting on the sealing surface. Use some 600 grit emery cloth to clean it up and re-evaluate.
