I used to have a vibration around 40 mph and thought it was the front driveshaft, so i got that replaced and now i get it at 60 mph. Now a couple problems: I relocated the trackbar when i put my 3.5 lift on, my front tires are bald! and last time i was at the mechanic he said my front diff was making a weird noise, also have a t-case drop in as temporary untill i get $ for an SYE. If anyone could help that would be awesome,im gettn so frustrated fixn my jeep recently.

 

steering stabilizer....

 

I got a new heavy duty one

 

It's just the Earth cowering in fear from the power of the 4.0. We all have that problem. Especially me.

 

could be bad balanced tires, your lack of sye, a u-joint.... kinda hard to diagnose a "jeep vibe" online since jeeps are everything short of a trojan vibrator.
