Jeep popping noise (video inside)

I need help diagnosing this popping noise. It only seems to happen when in 4lo and when climbing a steep incline. All u-joints and suspension components seem ok. The Jeep is a 1998 cherokee with a Rusty's 6.5" long arm lift and 33" tires. See video.

Exactly where is the noise coming from ? If it is coming from the center of the Jeep, you probably need a new Transfer Case chain. If you watch, you will see the T-Case jump when the noise happens. You probably can feel it by holding the T-Case shift lever.

If the noise is coming from the front axle, your coil springs are probably binding on the bump stop cups.

.

A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.

Its hard to tell where it is coming from mainly because i cant duplicate the noise regularly, but it does seem to be coming from somewhere in the front.

Put it in 4lo and give it some gas with you foot hard on the brake and see if it pops then. Be careful doing this and make sure nothing is in front of you because the brakes won't hold you back in 4lo if you hit the gas a little too hard!!!

Me too haha. I dont get the noise in 4 low and holding the brake so i don't think it is the transfer case. The more i watch the video it seems to be suspension related, but what in the suspension could make that noise? I can fully flex the suspension without issue, but when it is put under load (when climbing a uneven steep hill) i get the popping.
