I noticed this a little in the winter... but... I put it in 4WD to pull a small stump out of the ground... all went well until after I was done and I turned the wheel a lot to move the Jeep and there was a lot of loud popping and snapping and squealing sounds coming from the front end and the steering wheel shimmied back and forth violently... Once I took it out of 4WD everything was fine...
Any ideas what could be wrong with my 4WD? |

Interesting.. It sounds almost normal to me. When TJ is in 4wd, front and rear drivetrains are locked up together. When you are turning, front and rear drivetrains spins at different speed.
As the speed differentiation has to be compensated, you hear loud bangs through the drivetrain slack and tire squealing. This is a lot more obvious when you are turning.
Engage your 4wd and drive straight. If it doesn't make any sound, I would say you are good. Otherwise further inspection is recommended.

It is not as obvious when you are driving on loose ground as driving on tarmac.
I don't want to misguide you here. I said loud bang, but it is more like clunk... depending on how loose the chain is on the transfer case, it may have to do with how noisy your drivetrain will be. It maybe entirely because of the loose U joint at the outer stub of the front axle shaft. If it has developed looseness inside due to wear, it may cause popping and such just like the CV joint of the FWD vehicles.
If you get a chance, I would put the Jeep on the jack stand and roll the wheels on its power when 4wd is engaged and see how it does and also check for looseness of the U joints in the front axle shafts.
