Just put a 3 inch Lift Kit (Rought Country) on my 200 Cherokee Sport. When I am driving down the road mainly at high speed. Around 60 mph I hear a rubbing/vibrating sound coming from the rear end. I checked all the bolts and everything is tight. It sounds like I hear the drive shaft is what is making the noise. If that is the case any one got any solutions or something else I can check. Noise was not there prior to the lift. Any help would be greatly appreciated.

 

It sounds to me like your pinion angle is off. You could shim the axle. Or get a t case drop. At that height 1/2" of drop on the t case should be enough.
