Hi everyone, this is my first post here. Please bear with me as this will take a little explanation. I have an 01 with the I-6 and manual transmission with the Dana 35 and 307 gears. She was completely stock when I got her. Last winter, the rear diff started making an ominous noise and turned out to be the pinion bearing on the Dana 35. Since I wanted to put in a locker, I elected to get a Dana 44 from ECGS with an ARB locker and 410 gears installed. I also decided to install a lift so I got the 2 inch OME kit with JKS adjustable track-bars and disconnects. I've never done this kind of work on a vehicle before and it's been an adventure but the knowledge I've gained has been well worth it. Now I've run into a problem; I can't get the drive shaft to hook up with the differential. The control arms are all hooked up, the shocks and springs are installed, and I have the anti-sway bar installed on the axle but not hooked to the frame yet and the track bar installed on the frame but but not hooked up to the axle yet. Now, the jeep is on jack-stands and the axle is in the absolute lowest position that it can possibly reach and the u-joint on the driveshaft runs out of travel before it will achieve the angle necessary to couple up to the diff. If I jack up the axle, the shaft will couple up but I can't believe that the driveshaft u-joint should be the limiting factor on downward axle travel. I don't know that is supposed to be the limiting factor. I have not set the tj down on her wheels and tightened the control arms and shock bolts yet. Do I need to do that before trying to install the drive shaft? Thanks in advance for any insight and advice you guys can give, I'm stumped.
