Replacing a pinnion seal

Actually, threadlocker wouldn't have any bearing on whether you reuse the crush sleeve or not. The nut will not stay on any better with a new sleeve versus an old one. However, they do recommend replacing the pinion nut when it is removed and the new ones have threadlocker already on them.

I have crushed a new sleeve with my coupe on jack stands and no air tools. Definitely a pain in the ass. I had to fabricate a steel bar that bolted up to the pinion flange to keep it stationary while I torqued the pinion nut. I think I read somewhere where it takes around 280 ft-lbs to crush the sleeve.

Yes, it is some outrageous torque number...hard to achieve under a car.

But my 9" will allow me to set all that stuff up on the bench.

do you need a puller to get the flange off of the pinnion gear, or can you pill it off by hand?

depends on the car. I have worked on some that the flange would slide right off and some where you had to tap it for a little bit with a hammer

You'll prpbably want to have a puller available.

Thanks for the help guys, I will probably do this the week after we get back from vacation (about 3 weekends).

I might have more questions when the time gets closure, so keep an eye on the thread.

I am looking at doing this over the weekend.
Reading back through the post, I think I should use lock-tite on the pinnion nut (blue) and from what you guys are saying, it sounds like the nut will have a fairly low torque value, is this correct?

I am thinking of renting a dial troque wrench to measure the off torque to get an idea of were I should put it back to.

Any additonal insight on the pinnion nut torque (measured value) would be helpful, otherwise I will just wing it...and hope for the best.

Sorry, forgot to add does anyone know the torque on the differential pin bolt?

As I recall last time I used blue locktite, and a torque of around 30 ft. lbs, but I can't remeber for sure.

tighten enough where you can still rotate the assembly with a little resistance. If you can't rotate it then it is to tight

Craig is talking about the bolt that holds the pin in the carrier.

If you use a new bolt, the thread locker is already on it. If you're reusing one, just dab a little blue locktite on it and tighten with an box-end wrench. 30 ftlbs seems awfully much for that small bolt.
