Okay, my situation is that I have post lift vibrations. A 3" Rough Country Series II lift with netted after settling about 3+". My problem is I am getting vibrations at 30-35mph and then again at about 55mph and up. It does settle down when I'm not on the throttle but, doesn't disappear. I just checked my track bar and the ball joint end when pushing up and down on it is definitely shot. I also have a little play in the steering.
So, here is what I have been told so far. I have been told that the trac bar can cause this and also maybe be the tierod ends. I have also been told that a Transfer case drop will solve this as well.
My question is, can it be all the above and/or just the trac bar which I know is shot?

Help please. Any and all advice is greatly appreciated.

Vibrations are not usually from track bars, they cause steering issues and DW. the vibration is probably coming form the DS. fix the tack bar and see if it goes away but my guess is you will need to drop the transfer case.

Fix the track bar then put new u-joints in the rear driveshaft.
 
hoestly most people can not tell the difference between DW, tire/wheel vibes, drive line vibes and alignment related vibes

so this is my one size fits all vibe/wobble fix it check list...

raising the truck and putting bigger tires can make issues that are already there seem more serious... it also throws angles out of whack which makes things even worse

the first thing you need to do is this

1.) identify when the wobble is present

2.) identify when, if ever the wobble is gone (expamples, below 30mph, after braking)

3.) identify what action start the wobble (examples, hard turns, speeds of 45-55mph)

4.) try to swap out your tires for your full sized spare, do this one by one, chances are you will find a bad tire

5.) jack the front end up and check for anything loose (ball joints, bolts, etc)

6.) if you have not had your caster adjusted, DO IT YOUSELF AT HOME AND SAVE SOME MONEY

Thanks for the check list, I will use this to help figure out what is going on. I have already done some of it.
