Default transfer case is leaking

The past couple of months i've noticed spots under my truck. I figured out it was the front output shaft seal. I thought I could change it by taking off the front drive shaft and pulling the yoke out, but that didn't work. I went to a few local shops and they said that to change it they would need to take the transfer case off and open it up to get to the seal.

Could this be a weekend project that I could do or should I just let the shop change it out? Or would it harm it if I just let it leak and added oil whenever it needs it.

Default Re: transfer case is leaking

DON'T just let it leak and add fluid, exploding transfercases suck.

Pull the tcase out to do it, its easier than you think.

Remove both driveshafts
Remove tcase linkage (ifmanual shift) It just pops out with a screwdriver
Disconnect speedo connection and probably 1 or 2 other connections, screwdriver
Possibly have a vent tube to remove as well on top, screwdriver
6-bolts hold the tcase on on most. either a 9/16 or 5/8 flex-head ratchet wrench will be very handy.

The tcase will slide right off as the drivetrain has a very slight rake, so be prepared if it starts moving when the last bolt comes off. Be careful to slide the unit STRAIGHT back then down, so as not to damage the tcase input seal (that you should be replacing now as well)

Takes about an hr to pull with hand tools, no jack needed. Tcase is under 100lbs so you CAN lower it onto your chest and the push it off you onto the ground and pull it out.

If you have a friend to help it'll be a piece of cake.

I'd highly recommened replacing the tcase front input seal (just pries out and pushed in) and the rear driveshaft output seal as well, since the case is on the ground.

I like preventative maintanaince, did a Tcase front driveshaft output seal on a 6.0L Yukon last week and we went ahead and did all 3 t-case seals, and the tranny output seal (since it's RIGHT there), for a customer who saw that seals are $20/ea and labor to drop a tcase is not.
