2G Output shaft seal leaking

[1fast97gsx]

Mine is dripping, only a few drops a day but it still pisses me off. I had the whole trans rebuilt (I didn't want to really learn on my own :laugh and I got it back and put it on and put fluid in it. A few days later it started dripping and it's been doing it ever since.

It's no big deal but I still don't want it happening. The car hasn't been driven yet since the rebuild so it's just been sitting. Any chance if it sealing up from the heat and movement after I drive it around a little? What if I just put some of that stop leak stuff in? How do you just replace that seal?

I really don't wanna take the trans off or apart until I change a clutch again at least ... Thanks.

I had problems with trans fluid dripping out of the shaft seals (1G AWD) and the thing that fixed it was replacing the seal with a new one. One of the seals has a metal lip on it while the other one doesn't. Be careful that you don't pound the one without the lip too far into the trans when you install it. Also put a light coating of grease on the seal and slide the axle thru it very carefully so you don't damage it.

the axle? I'm talk about the output shaft seal ... the output shaft being the shaft that plugs into the transfer case, not the half shaft or axle.


Can you remove this seal with the trans on the car still and replace it? How? Thats what I'm asking. Thanks.

Sorry man, I misread your post. I never had a problem with the output shaft seal, but replacing that with trans in the car is gonna be tough. You're probably gonna have to unbolt the trans so you can take the cover off that holds the seal...

I dont know about the 2g, but the 1g tcase can be unbolted and removed with everything still on the car. You just need to be able to get under it and make sure the shaft separates from the tcase or there isnt enough clearance between there and the oil pan. If I run into this when I get my car running it's off to the dealer to have the tcase replaced under recall!

so basically, anything ever goes wrong with the transfer case, its covered. i need to fix mine, but idk anything about the transfer case, just that it leaks

To replace that seal, you need to pull the tranny out of the car. With the tranny in the car, you can't get in to that seal to pull it out (at least, I could not).

You just had the trans rebuilt and it leaks? So take it back and have them do it right!

On the 1G you won't have to drop the trans to get to the seal. Just remove the transfer case. There isn't a whole lot of room with the flywheel right there, so use a dental pick or something similar to get the seal out. Be careful that you don't scratch the sealing surface of the output shaft. Check the output shaft to make sure it doesn't already have a scratch that would cause a leak. I like to use a light coating of RTV around the outer surface and lube the inner surface of new seals. They press in much easier and you know they will seal with no leaks.

Well with the transfer case off I can see the seal. The flywheel isn't really in the way too much, however I don't know how to actually grab the thing and pull it out. You guys just poke a hole in it and pull? How tight are those pressed in? I'd rather not take the trans off again

I have to retract my previous sentiment that it would be relatively easy to change that seal with the trans on the car. It's been a while since I did the job and I just had a closer look at it. The seal is recessed deeper than I remembered. I had the center shaft out the last time I did the job and that made it easier. But I still think it's possible.

I think it might work better if you use a thin angled pick and carefully slide it between the shaft and the seal. Seals have a metal shield placed halfway between the outside and inside edges, so you won't get a pick through it there. The inside edge is the softest, and it will be harder to scratch the shaft than it would be to scratch the aluminum case if you were to try to pry the seal out from the outer edge. You'll still have to be very carefull that you don't scratch the shaft, so don't let the pointed end touch the shaft. In fact, you don't need a sharp point on the pick anyway. Just make sure it is narrow enough at the tip so it can push through the edge of the seal. Once the pick is behind the seal turn it 90 degrees and just pull the seal out. Clean the area very well. Remember to drain the tranny first cuz oil will come out here.

ok cool. Thanks.

you can use 2 screws screw them in a little and pull it out the screws will be 180degrees apart. thats another way to. if you get the leak again i would say there is a small imperction on the shaft that you can't see thats causing the seal to go bad. good luck seal leaks are a pain sometimes you would be surprised the things people try to do to stop them. shimming the seal, even recessing the seal more kit is the most i have seen and they still leaked

i just did mine last weekend with the trans in the car...to get the seal out i just jamed a screw driver in the side and pried it out (you will tear up the seal but that obv. doesnt matter since you are replacing it) then i cleaned all around the area where the seal goes in and outside of it really well with some q-tips and paper towel....

to get the new seal in you have to be kinda careful. as you already noticed the flywheel is right in the way, and you have to angle the seal to get it past the flywheel and it will still rub pretty hard. i put a little grease on the part of the seal where it was rubbing against the flywheel to help it goes a little smoother, but it still kinda scratched the rubber, but not that bad..i just put that side of the seal on top. then to get the seal in place just take the blunt end of something and lightly tap around the seal till it gets all the way in....just to make sure i used the q-tips again and layed a little rtv down around the outside of the seal in case when i was putting it in any of the rubber got damaged.

it would be 500% easier to do it when the trans is out, but as you can see its possible to do it while its in, just take a little more work.
