86 4x4 transfer case ??
 
I bought an 86 4x4 and the transfer case is leaking real bad (the seller informed me of the leak before i got it) my question is this a complicated fix or is it as easy as taking it out opening it and reseal it

Can you still drive it as long as you do shift into 4 wheel drive

ive noticed a decrease in my over all trans fluid so im guessing its all together so keep a real close watch on your level and id say it would be ok to drive.

do you know what seal is leaking? if its one for the drive shafts its ez. if its the main case its not hard but will take time to get it to line up

mine is dripping from the bottom bolt right where the metal guard is. I'm really not sure if its a gasket for that or a crack in it or what.

i called a shop and they said 600 to take it down and put a new gasket in it. So pretty much i can deal with it for that kind of money.

Although i was just reading another thread talking about the same thing and that guy had everything rebuilt and its still leaking.

It matters which seal is leaking like 86c20 said, do yourself a favor go get a couple cans of break cleaner or a degreaser and pin point exactly where it is coming out at. If it is from the driveshafts you don't even need to drop the transfer case.. And the transfer case is heavy as hell don't pull it out unless it is really neccessary
bigblue87 I don't know what metal guard your talking about? Like the crossmember it sits on, or the mount in between it and where your transmission connect? if it is coming from the crossmember it might be the front driveshaft which isnt that bad, if it is coming from the rear of the transmission then your in for some difficulty.. Just try and find out a location of where it is coming from. I doubt it is cracked honestly. you probably have a NP205, or 208 which both are tough casings.

I had a front driveshaft seal leak, but it was because the t-case input seal for the transmission spline had failed, letting the tranny fluid make its way into the t-case. It then forced its way out of the front drive shaft seal. So if your going through trans fluid then your pulling the t-case.
