Wheel Hop after Switching Out of 4WD

hey guys. had the 5.9 for a month or so now, and just for the first time yesterday i put it in full-time 4WD (it has 242 swap). well, i got back to my house and put it back in 2WD, and when i was backing out of a parking spot later on, it felt as if the wheels were hopping as i turned backwards out of the spot. almost felt like i was trying to back up over a curb or something as well. i tried to replicate this and it did happen again, except the next time, i switched back to 2WD, then just took a semi-hard turn and the wheel hop happened again.

whats the deal? is this something thats normal, as it goes away after a minute or so?

Looks like tcase sticking in part-time 4WD. Try going in/out 4WD modes when going straight at some speed, not at standstill.
If it's stuck in part time 4wd, try reversing and going forward, sometimes that works and you'll hear a click from tcase.

PS: FULL-TIME 4WD is 2 clicks back from 2WD, PART-TIME is 1 CLICK. Sure youre not messing them up?

Shaban is pretty spot on.

Yeah, I'd say it's pretty normal. My XJ with the 242 would do it sometimes too. I think what happens is when you shift from full time to 2wd you have to go through part time and for whatever reason it gets stuck in part time. Moving seems to help. You can also spin the tires and it will shift. Also check your tire pressures. On my XJ I had a bead leak on the one rim and it made the transfer case shifting a lot worse when that tire lost a few pounds.

the 242 is supposed to be shifted while moving and if you hesitate in the pt position it will shift to it.

if your tires aren't exactly the same all around it'll hang in part time. usually backing up for a ways will free things up, or goosing the throttle, popping it into neutral, then back into drive while moving will get it out of part time as well.
