So for no apparent reason, my transfer case started leaking and leaking pretty good. I'v only had the jeep a month but this just started. Any idea why? I did take it out and put it in 4 low for the first time? Any ideas as to why i is leaking would be appreciated. btw it appears to be leaking where it connects to the transmission.

I am removing it and just hit my first roadblock. Disconnecting the drive shaft I'm not sure what the little bolts are that are holding yolks on. I'm thining mabe 12 points? anyone have an idea of what size? here is a pic20140213_131311_resized.jpg20140213_131413_resized.jpg

So what are these little bastards? any idea?
 
started leaking most likely at the front output seal since it has not been used in a along time and now turning for the first time in a while
 
OEM bolts....wow! As long as you are in there...what upgrades are you thinking about?
 
Drive shafts are disconnected and the 5 bolts (or am i missing one) that holds the transfer case to the transmission are off. I'm guessing that I now need to disconnect the 4wd lever from the Tcase? Is there a trick to this or one place to disconnect that is better than another? also, what can I expect and is there an order things need done in?
 
p.s., if any one has the patience, time and expirence, I would lve to have someone on call. my number 505-787-6342. feel free to give me a ring.
 
Ok, I have the shifter disconnected, it was just a one bolt deal. I think it might have been leaking because the 5 bolts that connect the tcase to the trans, the top were nice and tight, but the bottoms ones were quite a bit looser.
 
Correct me if I'm wrong, but isn't there supposed to be a gasket between the tcase and transmission? Also, should there be a pool of oil?

The worst part about this whole job so far? trying to gt the tase down when it was pinned by the aftermarket exhaust!

Alright jeeps what do you think/say?
 
There is no gasket between the two because there's not supposed to be any oil between them
Maybe your transmission fluid leak from the seal that the transfer case inserts into

I took some time to de-grease the tcase and there appears to be a leak somewhere around the bearing where the rear drive line hooks up to ad possible where there is this plug (don't know what it is) that is covered with silicon.

This is the silicon plug

This is the leak I can see, where the rear drive shaft connects to I hope I didnt do any damage while getting it off the jeep and jimmied through the exhaust

Inside the transmission I don't see any type of inner seal?

Thoughts and comments?
 
20140213_162822_resized.jpgRandom plug, don't know where it came from or what it is for. will probably be ignored as I don't see anywhere for it t connect to the tcase
 
the circle outlined in green?

Ok what about the oil dripping from the rear out put? also looks like oil is beading up at the base of this little nozzle where it screws into the main housing
