Transfer Case leaking fluid at rear output shaft

I have my transfer case off my Wrangler. I set the transfer case on its end for a few moments and a large amount of fluid leaked out around the rear output shaft. Would that indicate bad seals or would it be normal for the fluid to leak out while in that position.

Was it leaking while in use?

It wasnt leaking when on the vehicle. There is a seal on the back that looks like it might seal against the drive shaft coupling. That is what makes me think that maybe it would be normal to leak until the pieces are put back in the Jeep.

You are correct. While you have it out, why don't you replace that seal for about 10 bucks.

Yea, I think I will take your advice on that. Thanx...

I have a theory that if you are looking at an inexpensive part that is difficult to get to, change it. Especially if it could cause lots of damage and/or strand you in BFE.

Bushing

There will always be a little fluid left after draining it. I would suggest changing the bushing in that rear housing as well as the seal. If the bushing is worn it can lead to the seal leaking prematurely. I just changed both of mine. I used a 30mm socket to drive the old bushing out. Anything larger to drive the new bushing in is fine.

There is no need to change the bushing unless it's galled or worn oversize.

I would definitely change the seal though. It's cheap insurance.

If you don't change it now, it's no big deal to drop the rear shaft and replace it later. It's not like it's really hard to get at like some other seals (input shaft seal for instance) while it's in the vehicle.
