As for the vibration, try removing one drive shaft at a time and test driving the Jeep. If the vib goes away, you know you your issue is with that drive shaft.
Try rotating you tires back to front. If the vibration changes or goes away, you can get your tires balanced. If none of that works you'll want to look at axle U-Joints
? Hopefully you track down the issue with one of the first two suggestions. Good Luck and let me know if you have any questions!
