So ever since I lifted my jeep there is a vibration that only happens when I get on or off the throttle. I have just replaced the axle u-joints today and its still happening. It does not do it as much cold as when its warmed up, and it only happens for a second or two the instant i am on or off the throttle.

PLEASE PLEASE help i am at my wits end.

Check your Motor mounts. There is even a write up in the write-ups section for replacing motor moutns

How much lift? perhaps you need a Tcase drop?

XJ Stryker

Why would he want to drop the t-case if he just lifted. If the vibes are in the rear then you would want to consider a SYE or getting a better drive line angle by adding a degree or two to the shims.

T-case drops are a waste of money.

Sorry i forgot to mention it's a 3'' RC lift woith the full leaf packs. Its so hard to tell where the vibration is coming from.

because it lowers the driveline angle getting rid of the vibe
hence not being a waste of money
