Thanks for the help and sorry for the trouble.
You shouldn't have driveshaft vib issues with a 3" AAL.

Take pictures, that will help a LOT.

Is the pinion yoke pointing at the t-case output?

I've got another question with the SYE.

I put in the Iron Rock Offroad Hack n Tap sye when I did my lift. And it got rid of the vibration and it's fine now. Since I have this does that mean I can go higher without having to worry about the driveshaft anymore?

Has anyone installed the rc 1.5 -2 " shackle? I just got mine, it came with four bolts, a metal sleeve, and four poly gromets. My questions are what do I do about the top bolt? The nut is welded in but the kit came with 4 bolts and 4 nuts....
Other one is does the metal sleeve go in the poly or down below?

Just reuse the factory top bolt and the metal sleeve goes on the top. The other end is the rear pack which will already have a metal sleeve in it.

The axle is definitely pointing the wrong direction. From the looks of it the pinion angle needs to go down at LEAST 6 degrees, maybe more.

I couldn't tell you without getting under there with an angle finder.

hmm, you shouldn't need to adjust the rear up or down much at all, i've got 5 inches of lift with no vibes. Have you checked the U-joints, mine were vibing bad, changed them, no vibes. I didn't read through this thread so i don't know if you have canceled that out yet. Just throwing something out there, but that looks like its way to far up. mine is nowhere near that

well yeah, thats because he put the shims in. if he had an SYE it'd be damn near perfect.

I put is a RE 3.5 lift and took the vibes out of a '99 with a Rusty'd 1" cross member for the transfer case http://rustysoffroad.com/mm5/merchan...y_Code=xj_skid

So to answerr your question yes do the cross member 1" drop it is worth it, easy to do and you will have a stronger cross member too.
