Measure what you need. I had to us a wj one in mine.

 

I'm pretty sure I had it extended to about that of a ZJ. Since I pulled the wrong size ZJ shaft at a JY. I pulled it off a straight 6, I guess the V8s are longer? Anyway, I had a shop use that ZJ one and my front XJ one and they retubed/extended it to I think 33'' or so. I think it was fine when I installed it. I don't recall it being compressed. This had to have happened when I moved from a 6.5 pack to a 3.5''.

 

That shouldn't make that much difference. I went from 7" in the rear to 5.5 ,3.5 re leafs and a 1" shackle. And used the same angle on my 8.8 and the same drive shaft. Loosen the eye bolts and cycle the leafs on the ground before I tightening them.

 

Loosen the u bolts? I tightened the u bolts when I had the axle jacked up to tire height. I tightened the front and rear leaf bolts when the axle was lowered. Possibly the issue?

Ya the bolts on the springs. Also I read you have shackle relocations that pushed my last set up forward about 1.25". Your in the Chicago area right? Elgin drive line is awesome my dad's done business with then for 20 plus years. Iv had them build me drive shafts and u bolts great people.

 

So you think the relocation kit pushed it forward? I can see that happening. I actually had a custom shaft made from extending two front XJ shafts at Suburban Drive Line. They retubed one and extended it for like $300 and it's essentially a new custom shaft. A buddy had a custom one made from them and it cost him $400, so.

Should I move my shackle back a bit? Would that help at all? Trim my slip yoke some?

Here's how it looks.

 

Moving the shackle won't do anything I don't know about the slip yoke. I have a slip yoke eliminator so I don't know

 

Post a picture of your hack n tap, lets see how much of the output shaft you still have to work with.
