This weekend I was trying to replace the u-joint on the back axel driveshaft at the transmission, when I pressed the new caps in enough to get the clips in, the joint would freeze up, not just get stiff but lock down. As soon as I took one of the clips out and moved the cap it was fine. The new joint was a Moog the only thing the Nappa or Advanced had. Can anyone recommend a better u-joint. This is on a stock 98 TJ
