Where is it smoking from?

Youre not trying to use it on pavement, are you?

smoking out the tail pipe
yes i was pulling a tree stump out and it was on my driveway.. only going straight tho no turning

you pulled it in 4-Lo right?

Even if youre going straight, its not supposed to be used on pavement AT ALL. Unless you have the 242 with FT 4wd... Good way to grenade your tcase.

Blue smoke, black smoke, or white smoke? lol

white smoke... and like i said only when in 4h/4l

well since this is my first jeep i didnt know that..

Notice any loss of coolant, or milky oil?

no its not a head gasket... no coolant loss no milkey oil...

if that were the case it would do it all the time not just when i engage 4h/4l....

Well its not the transfer case smoking out your tail pipe. White smoke is water, blueish is oil, and black is fuel (rich) or carbon. Its probably the head gasket, its just doing it when the truck is straining more. And its probably slight right now so that's why you don't notice the fluid going down.

You can have someone pressurize the system and see if it holds.
