Default 2 inch lift and 33...now vibration and noise

Put on a 2 in daystar lift and 33 inch Nitto Graplers and getting a lot of vibration and noise when in idle reverse. Also getting some noise and vibration in idle D but not as much. Could be gears or timing? It's a brand new 2012 unlimited. Any help pleas. Thanks!

Could be a coincidence or maybe something is loose under there. Turn the Jeep on and get underneither and see if there's any obvious loose bolts, brackets, exhaust etc that could be causing the vibration. Check all bolts on the suspension as well to make sure they are all tight. Put the vehicle up on jack stands (all 4 wheels in the air) and have somebody put it in D and let it drive itself while you watch the driveshafts turn and look for anything that isn't right.

The other way to do it, is just take it to the dealer if it's new.

True that. But I've heard of dealerships voiding even the axle and steering components from a lift..
