popping noise
Hey all,
A while back I asked this question is a longer thread but thought I'd start a new one specific to this (rather than the list of issues I had before). Here's the issue. After the engine is warm and I come to a sudden stop (normal braking) I hear a popping/cracking/bubbling noise coming from somewhere beneath the shifter or 12v outlet (best position i can gather). For a while I thought this was just a small hole in my exhaust causing all this noise under back-pressure created from decelerating 45-0. But after further inspection, if i wiggle the shifter while in 2wd it goes away. With this discovery I assume it's something transfer case related.
Any thoughts on what could be going on here?-Matt

Re: popping noise
I should note that the vehicle runs perfectly fine, no knocking on the U-Joints. or anything. I'm also not doing a lot of shifting of the t-case and overall don't drive it very often even though it's my DD (we have really nice public transit out here) so it's pretty much a toy at the moment. If this is a malfunctioning t-case what damage could it do? Also, are their any good way's to check it without tearing everything apart?
Thanks in advance,-Matt

Re: popping noise
From other forum's i've narrowed the issue down to bad bushings in the linkage. Quick question if anyone is following this. Does your t-case lever have any play in it when set to 2wd?
Thanks-Matt

Re: popping noise
Did you install a transfer case lowering kit when the lift kit was installed?
The transfer case shifter linkage is a goofy setup, connected to both the transfer case and the tub. Any interference with the shifter bellcrank or worn bushings will cause some strange noises.
