Oh, and do you have any more pics?

 

Its a real good lift my only quarrel with it so far is the heim joints, they seem to wear out and rattle realy fast. If you do get it a good place to get get replacement joints is http://www.currieenterprises.com/ces...nnyjoints.aspx
Alot of flex in it the truck can tuck the 37's with nothing hitting just fine, dont have any pics on this computer

 

thats one nice looking short box. i would never have though a 7'' lift would look that nice. make me want to lift my truck.

 

id check the bearings on slip yolk in the transfer case

i've said it before, these trucks have the same case as most Cherokees, with that much lift, you're liable to shred the bearings, which can cause the transfer case to lock up

the noise/vibrations you mentioned are a common symptom of bad bearings

 

yeah i just had the transfer case completely rebuilt, noise still there, doesnt do it with the driveline off, just replaced the U joints still does it >_< lol. now i cant get it to stop leaking where it bolts to the tranny, and i replaced the rear output seal in the tranny >_< im just gonna drive it until something falls off

 

So when you drive with the rear shaft off the vibration goes away? Have you checked the balancing of the rear shaft? Is the little balance weight still there? Its possible that it got knocked off somehow and it is no longer balanced.

Good luck with finding the culprit man. Little things like that can drive a man crazy. But, I am still sticking with my guns and saying the angle of the shaft due to the 7" lift is not the issue (unless it was improperly shimmed).
