Sounds like the splines on your transfer case gear are ground down

sometimes if it has automatic lockers you have to put the jeep in n then switch to 2h then put in to reverse to disengage the lockers then your good to go and if you put the 4wd in n instead of 2h you wont go anywhere its n for everything you have to run in 2h on the hwy

i just bought a used 97 CHEROKEE but i had the same problem, when i got to looking at it i found out the front driveshaft was shot, look at that, if its not it i would say its probably the transfer case especially with an older vehicle like that which is a very expenxive repair

sound like over filled. drain out fluid change fluid and filter put the right amount in it.

check to see if front drive shaft is locked in by spinning it by hand, if it is there is a sensor on top of the tranfer case that has the vac lines connected to it. On the bottom of the sensor there is a ball. If the ball gets stuck open the vac stays on and the front end stays engaged no matter if your in 2 or 4. The sensor is like 22 dollars from chrysler.
