Chasing noise for a year now.
I have a 2002 TJ with 6 1/2 lift. Quick story to the prob. Last winter I had a truck slide threw an intercetion on ice and I was in 2wd, I hit the gas to get out of the way and spun, yanked the lever into 4x4 while on gas ( yea I know ) and got out of the way before he hit the bank beside me. 2 weeks later my axle backed out on me. Replaced rear axles and bearings. Road test, all good for about an hour and out of know where a loud bearing noise started. Since then I have replaced the trans cause the shifter was shaking and noise is there in 3rd,4th and 5th. Noise still there. Replaced trans case, noise still there. Noise is only there in 3,4,and 5th, all driveline has been replaced except fron rear and u joints. Noise sounds like a loud Pinion bearing and goes away when you let off gas. HELP!!!!!!!!
