I don't believe that I needed to trim anything off the shaft on mine. Some transfer cases you have to trim and some you do not, depending on how much the shaft sticks out. It is my assumption that I probably wouldn't be able to shift into 4wd if you have to trim the shaft and did not. If I remember correctly i was supposed to measure the shaft to see if I needed to cut it, and I think it was ok. In any event, it had been in and out of 4wd all winter with the sye installed so I am guessing it is probably fine. I suppose I must not have tightened the plug all the way, and never rechecked it after the install???? Either way, it came loose somehow, and I am just happy I noticed the slow leak this early, instead of all the aft draining out on the highway, and blowing the Xfercase apart. I still need to wait another 30 mins to call AA when they open, so I will try and figure out a aolution from there.
Another person posted to check the FSM for the part. There should not be any spec for that part, as the jeep was not equipped with that from the factory. Thanks for the replies.
