Well the roads are snowy here in buffalo and i noticed that when in 4wd once i get to 25+ i start to get a vib in 4wd. its gets worse with higher speeds and doesnt exist or is not noticable at low speeds.

out of 4wd no vibs

i do have a lift 3 in the front 4 in the rear.

what do yall think?
 
ima do a little more inspections on when the vibs come go and get worst. in this weather its tough to do under car inspections
 
i would definately check all your u-joints up front
 
on you jeep the front axle is disconnected when you are in 2wd and the front drive-shaft does not spin. so the u joints are the culprit.
 
If its lifted, the pinion angle is off and is what is causing the vibes. Other than that, ujoints or an out-of-balance driveshaft. Pinion bearing also could be the culprit.

You definitely have the 231 tcase as it came with a disco d30, which is why you're not feeling it in 2wd. The 242 came with a solid axle up front.
