Pinion Seal Leak After Rebuild!!?? Help!
I had help getting my rear end rebuilt by an experience guy. And I dont doubt his abilities but, its slinging oil from the pinion seal...I'm pretty sure. Where else would it come from? Its not coming from the diff. cover. Its slinging all under the bed. I'm going to get under it this weekend. While I had the rear end out I put in all new lowering springs, shocks, front and back and lowering blocks on the rear as well. I watched the guy who rebuilt it put a new pinion seal on it. But its slinging it not dripping...

it could be creeping up the splines and out from behind the washer and nut. i had a it happen to me. i smeared a little black rtv on the splines and under the washer and it solved the leak from the pinion.

Re: Pinion Seal Leak After Rebuild!!?? Help!
Thanks! I am definately going to try that next. I mean it is slinging it, would that come from a bad seal? Not sure where else it could come from. Surely it couldnt come out the vent in that vast amount!?? And I have read a bunch on here about torque specs and how to tight that nut needs to be. And they were all mixed answers. Any suggestions?

Re: Pinion Seal Leak After Rebuild!!?? Help!
i was worried about the torque also, i was told to just make sure the same amount of threads where showing and make it snug since the crush sleeve was already set. mine was dripping also but that was due to the pinion angle being almost flat(due to lowering). I actually just took the nut and washer off and smeared some in there. then when i built my next one i did the splines also. If you pinion angle is proper then the fluid should not drip due to it pointing upward, however when it spins the fluid could creep up. i doubt it would spew that much out the vent unless you grossly overfilled it. it could be the seal, but highly doubt full, you can change it while you have the yoke loose if it makes you feel better.

it should angle up slightly, mine had bags with no c notch, so ride height was about the same, never had any issues with the angle, just the leak, but once i did the rtv trick it did not leak again. you could use an angle finder(most home improvement stores have them) and check it.
