Death Wobble??!!

[TapouT]

I have a 1994 Jeep Grand Cherokee. I just got it lifted yesterday and it has a vibration to it. It's not like a shaking/shimmy type vibration it's just a vibration/roaring/grinding in the front end, almost sounds like it's coming from the driveshaft. It will do it while i'm driving down the road and then when I left off the gas the roaring will go away but then when I get back on the gas it starts roaring again. It has the rough country 3.5" kit with 1-3/4" spacers in the front and a 1" spacer in the rear. It also has a transfer case drop. What could the problem be? It didn't do this before the lift

rear drive shaft is probably at a bad angle try some adjustable rear upper control arms. Its not death wobble i promise youll know death wobble when you get it

is it going to mess anything up driving it like this?

Unit bearing? Lifting a vehicle always make worn parts more noticeable

sounds like your pinion angle is too low. when mine was low i had that exact symptom. id point the pinion up a little and see if it fixes it. if not then you may need a cv driveshaft.
