LOUD violent POP from transfer case on occasion from my lifted Rubicon transfer case
Hello. I just bought my first Jeep, I will make a thread as soon as I can load some pics, but right now I'm a little disconcerted by an occasional and loud "POP" that comes from the transfer case. This "pop" has come when I was shifting from reverse to 1rst, 1rst to 2nd, downshifting from 2nd to 1rst or just starting out from 1rst. This Jeep has been lifted 3.5", 2.25" of suspension lift, and 1.25" of body lift, and 1" spacers where placed under the motor mounts. I don't think anything has been done to the transfer case mount. The pinion angle looks pretty good, but it isn't straight line right now. The truck rides on 33's, and every time this "pop" has happened so far I was driving it in 2wd.
I plan on inspecting the transfer case for broken teeth but I haven't made it that far yet.
Any ideas? I need to figure this out before something breaks, if it hasn't already.
Does it seem to come up from the floor pan, under the driver?
If so, it could be the transfer case shift linkage. On a stock TJ, it's mounted to the tub. When a body lift is installed the linkage can get bound up and pop now and them. The solution is to use an adapter bracket that moves the linkage to not mount on the tub, such as the Advance Adapters unit.
