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'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
