Default Weird vibe in the rear...

So I just got done lifting the 98 (again) and now I have a weird vibe coming from the rear under accel. I thought the driveshaft was out of phase, but I tried moving it and it didn't work. Any other ideas? Lift stats to follow:
3" RC front coils
3" RC AAL on Quadratec HD leafs

Odd thing about it is it didn't do it before when it was the stock leaf packs w/ the AAL...

Good luck. I have changed everything, tried differant driveshafts, lowered, raised, changed and rechanged everything.
Im taking all of my lift stuff off so i can drive my jeep. Ive wrenched on it every day for the last 2 weeks, fed up. My lift parts will be for sale.
Had a Bronco, put 4" blocks in back and bigger springs in front with no probvlems ever.
XJ"s are too touchy, too hard to get perfect, too expensive to just try this and try that.

As much as I love my Xj I slightly agree with you about the touchy part.
