rear end viberation
 
TJ Wrangler rear in vibration and noise. I checked drive line and put it up on stands turned wheels all seems OK. I've checked it rolling in neutral and the problem is still there almost feels like rear end is dragging but when moving at any speed it doesn't slow down. Any Ideas?

Was this always the case or did something change?

Sounds like a worn U join or wrong pinon angle. Could also be a bad wheel bearing. Is there enough fluid in the diff? Try putting the rear on stands. Try to wiggle each tire up, down, side to side. Spin each tire in both direction. Do they spin freely? If this is all good remove the rear drive line, plug the slip yoke, and drive in 4H. Is the vibration still there?

Another thing to check is bushings. All of them if you got leafs check spring, and frame mounts. Coil spring set up check all the control arms, trac bar, and sway bar.

Are you lifted? If so, how much? Could be lift related...

U-Join and fluids OK... Lifted 6" --- Problem started around the time tire rotation was done, the tire have always made noise on the hwy. but nothing else has changed. I've had it up on stands and all seem OK

Are your wheels balanced?

If you rotate the wheels back and the problem goes away then its in the tires.

Thanks for all the advise, I keep checking and found that my rear wheel rim was cracked. Never thought it would be that. Thanks again you kept me looking.
