Took the jeep to my Gear guy and we inspected the rear end
We got under it today and got the rear wheels in the air and applied brake pressure to simulate a load being on it . While sitting under it I noticed the clicking was coming from the CV joint/tcase output . So we take out driveshaft and inspect and seems fine , check yolk on output of sye and its fine. He said everything seemed fine .
So we check pinion angles and they are dialed in , measure the control arm distance (as I have adjustable upper/lowers) and they were exact .....we are stumped ...
so we are putting the driveshaft back on , connecting the cv end and Harry notices that one of the Ujoint clips is out of the groove above the cap . So I take a socket and hammer, while connected, and hammer on the clip to try and move cap back and click it in the groove. Well after some love we get it in and use a flathead to notch the bottom clip in ...and all of a sudden the NOISE IS GONE wtf!!!!
Could a ujoint clip in the CV joint actually cause this chatter and cause driveshaft to shake even the tcase???
never thought but I guess just the slight movement of the Ujoint up/down without the clip holding the one end in tight could cause .. so f'ing happy .... for now
Here is a video of the driveshaft under load and a pic .... just to get opinions on how the angles are ...thanks
