hello I have very bad vibrations on my 1999 xj. I just did a 2 inch lift and toke off my rear sway bar. Will this give me the very bad vibrations that I currently have?

 

Can happen after lifting since you're changing the operational angles of the u-joints. More likely to act up if they have some miles on them.
Nothing loose in the front or rear suspension I assume? When does it vibrate? Feel it in the seat? Steering wheel?

 

Did it vibrate before? Did you have it aligned?

 

After a lift get it aligned.

 

I did align it after the lift.I feel the vibrations in the steering wheel when I hit 50 MPH

 

Mine has always had a vibration at about 50mph in the steering wheel, even with i first bought it stock. it's only at 50 and goes away at 2mph+/-

Question is: exactly how bad of a vibration? mine is just a shimmy, very brief and my girlfriend doens't notice it. Sounds like it's not violent enought to be death wobble. When was the last time your steering stabilizer was replaced? What about your tie rod ends?

 

when I hit 50 mph it shakes so bad I basically have to almost come to complete stop for it to go away. it is very bad.

 

and steering stabilizer never been replaced. and I recently replaced both hubs and all 4 balljoints
