Lift kit update

The rear fabtech did recenter my axle in the fender well but now my driveline angles are off and I get some vibrations. I rebuilt the front and rear shafts with new U joints, lengthened rear 1", and balanced. Now to fix my rear angle I need to order some Zone offroad adjustable upper trailing arms. Right now my tranny differential to shaft is 6.6 degrees, shaft is 15 degrees, and rear end is 10.1 degrees. So obviously the tranny angle to rear end is off by about 4 degrees. I'm going to adjust the rear end down to about 6-7 degrees then it should eliminate the vibration I'm getting now. FTS offered to help me straighten out the vibes but Fabtech didn't offer crap. Zone was cool and gave me part numbers to order the specific parts.
