So the driveshaft bolted to to rear of the transfer case but it's too big for the rear yoke? Maybe their 2 different size u joints? I have a '92 and they are the same on both ends(1310). I would measure what you can, from the old to the new. I was looking for the chart showing dimensions of the different styles but can't remember where I saw it? Maybe somebody else has it handy..

Really not sure. Do you have the old one? Have you measured where it sits on rear yoke and compared the front?

87-93 has the 1310 joints, 94-95 has 1330. It's possible you have a Frankenstein Jeep, though.

Or you're confusing the fitment. Both 1310 and 1330 u joints have the same cap diameter. The 1330 u joints are longer, they have a bigger cross.

So you could have a u joint that you THINK fits, but is actually too long. At the transfer case, I think the u joint needs to be pressed into the yoke. I know the axle pinion yoke uses the straps.

On the pressed yokes, you'll have a groove where a snap ring will go. On the strap yokes, you'll have a small bump on either side. If the u joint is too long, and sits on top of it, it will give the impression that the cap is too big, when it's the length.

Also make sure the caps are seated correct on the u joint, and the needle bearings are straight.

When I reinstalled fits on drive shaft perfectly, hooking it up to rear yoke at the differential it's too small I hooked up the straps with one cap resting where it should the other cap has about 1/2 inch space.

Yeah there is .41 difference in width of caps after looking at that chart. Looks like you have 1310 and need the 1330.

Nothing has changed but the u joints right? You have to have the wrong universal. I'd go get the 1330 Spicer u joint.

Yes, sounds like you have a 1310 u joint where a 1330 should go. If you have a little less than a half inch play between the little bump things, then you probably have the 1310 instead of the 1330. Even if it stays put, it's not the right size so it's not very safe.
