A while ago I had a local shop install a SYE while I was in Iraq, it has been about a year now and my jeep has been in the shop about 6 or 7 times because it will not stop leaking!!! Lucky I have not had to pay for the extra visits but I was wonderin if y'all had any info on this it would be kinda cool to not have to take the jeep to the shop so much. Have any of you had any prob with your tranfercases leaking after the swap.

If it matters at all I got a 3.5 inch lift (RE), and a chystler rear end with 410 gears...

Pictures? Leaking at? Middle where case halves meet? Speedo sensor? Output shaft seal towards rear axle? Seal between trans/tcase?

I think it is leaking out of the middle I am going to figure out how to put pics up after school, does the shop have an obligation to make it right? I have never heard of a transfer case leaking I always thought that they were like rearends and were low maintnance and lasted?

the biggest thing is how you apply the liquid gasket. Often times, people just smash it together right after they get the bead down. You're supposed to wait long enough for it to become tacky so you're actually creating a gasket and not just squishing it out. The NP231/232 are not bullet proof by any means, there are more than a few things that can go wrong in there.

Just a thought…if it’s leaking out the middle between the transmission and transfer case. (not the middle of the transfer case)
Sounds like the rear transmission seal is leaking not the transfer case. There is a weep hole in the case so if the trans seal starts leaking you’ll see it.
That's my guess.

^that's a good point. At least in the AX-15 I'm sure there is one and it will leak if that rear seal isn't working right. The previous owner of my truck silicone'd a wire nut in there to stop the leak... I've since fixed that, but that's how I found the hole; giggity.
