Looks Well Made

Although not listed it does fit an xj. Appears to be pretty well made and should really strengthen my driveline and eliminate any vibes. Instructions that came with it were from the teraflex sye kit(not sure if thats even legal) and was higher priced than a few others. It was more difficult to remove the TC than install the sye. P.S. make sure you have a set of lock ring pliers, not just snap ring pliers.

awesome kit

This kit is awesome . Fit and finish was awesome. Heard of guys telling u that u can install with transfer in the jeep ... i dont see how ! Much easier to follow the instructions and remove it . ONLY thing i did not like was the kit includes 3 circle clips u need for install . One of which was good u can use proper circle clip pliers on .... the other two however .. were the kind that just had flat ends and are a pain to put on ... dont know why they cant put regular circle clips there too

problems

After install I drove a 1,000 miles to SO CAL. Upon arrival I noticed that the tailshaft housing that came with the SYE was leaking from a pinhole in the brand new housing. I called the nearest 4WP, Temecula. They didn't believe me so instead of them shipping me a new one overnight, I had to drive another 200 miles to show them. Then they made me buy a new one, and I was told to return the bad one at my convenience. HA! That night I installed the new housing and found that the machined hole for the speedo gear had not been done completely. There was about a 1/4" lip almost all the way around the hole. I did not have the time to take it back so I took it off myself with a chisel, flathead, and razor blade. It took me about 4hrs, and I was really angry, but it turned out pretty good. I plan on taking this one back when I find some time. Other than that it went in easy and it cured my driveline vibes. I would say that this is a decent SYE but I will not buy another PROCOMP/TERAFLEX . My father in law has an Advanced Adaptors, and it looks like a way better product. Unfortunetly I just heard that Teraflex builds AA SYE also. O' well it looks a lot better.

In combination with the CV joint drive shaft the Jeep now rides smooth and steady at all speeds.

A pain to install, but works great.

The instructions were not all the explicit and it took more then the 2 hours it said it would but the vibration is gone in the driveline and the strength is vastly improved....
