Driveshaft rebuild HELP

I am trying to rebuild the front driveshaft of my 2000 XJ. For whatever reason I cannot get the ujoints to line up on the double cardan end. I doesnt matter if I try to assemble it then install it on the driveshaft or try install the double cardon end andthe put the last u joint in. it seems like the center kit is sitting too high. I have tried everything and cannot seem to figure this out. I know I have all the right parts. All parts are spicer.

Assuming you have everything in the way it's supposed to go, all you need to do it compress the centering ball spring a little until holes lines up. Look here: http://www.stu-offroad.com/axle/driveshaft/driveshaft-5.htm

I just rebuilt the front shaft on my 01 TJ a few weeks ago due to the angry sparrows. Luckily, I took all of the parts with me when I went to get the new parts.....guy pulled out the 211355x and I compared it to the OEM piece I had and it was different. The cup height/shoulder area was about 3/8" taller on the new part. Ended up using a Spicer 211544x centering yoke that was the same height.

Compare your replacement part to your original and see if that's the problem.
