SOURCE: Transfer case leak
You mean between the case halves? It is just silicon, no gasket. These are good for the pump wearing a hole in the rear housing and leaking oil. The cure for it is a new rear housing and a piece called a case saver that keeps the pump from doing it again. Taking the transfer case apart to fix it is easy, I can tell you how to do it.

Sounds like the chain in the transfer case has broke or the linkage is out of adjustment

Sounds like you got it. They are heavy and ocward (spelling?). As for the front drive shaft take the bolts out and give it a couple of wacks with a dead blow hammer then slide it out. Maybe a few days before hand give it a good spray down with wd40 or like product. Also when you get to the last bolt for the t-case to trans loosen it half way then put a drain bucket under it and seperate it a little and let the trans fluid drain some, or you will be wearing it.

Try jacking up one side of the front and putting it on a jackstand. Then turn key on(but dont start it) and put it in 4hi. Try to spin the tire in the air. The drive shaft should not turn nor the wheel. If the wheel does then maybe the acuator is not moving in the axle. It worked when you pulled it out but it might be hanging up on something in the axle.
