Pinion Seal Replacement Instructions?

[zerbydd]

My pinion seal is leaking. I have been looking on the internet for some instructions how to change it. But that was for other vehicles. I was just hoping that someone could tell me some good instructions on how to change it. Thanks.

Ok, today a buddy and me changed it out and got it back in. Everything went really well, changed gear oil, crush sleeve, pinion seal, dif. seal. Everything went pretty good. I still can't drive it because I still need the heads. I don't have the money right now to go and get them and get everything back on. But when i do, i just pray that nothing else serious happens.

Well, we were watching the speed channel the weekend we did the pinion seal and we did not do it right. We have not driven it yet because i still don't have the heads on it. Well, what we did to tighten it up is taking a in/lb torgue wrench and me putting my foot on the brake while my buddy tightens to 25 in/lbs. Ok, we are done. Wrong, when we were watching the speed channel we found out that you need to have 25 in/lbs before the wheels actually start turning. Man i am glad that we haven't driven it yet. Well, tuesday since i am getting paid, i am getting my heads back. Oh i can't wait. I have been counting down the days.

Thats funny! Sorry, but I laughed....

If you simply torqued the nut to 25 inch pounds, then you have to tear it back down.
Once you get an actual rotating torque on it, its going to change the contact pattern of the gear teeth. (since you should have a new crush sleeve in it) The pinion contact pattern is going to move toward the front of the car. ("outer edge of the teeth")
