So under 55 no issues. I would check your rear driveshaft u-joints first. Then tighten up all the suspension bolts. Does it feel as if its in the steering at all? If you say move upto 60 or 65 does it get worse, stay the same.. or noway you even want to try that speed?

Same thing happen to me in December any speed over 55mph,the shake in the steering wheel was unbearable.It only had 1800 miles,took it to the dealership (warranty) and it was the right front rotor that was bad.......

When you cleaned the wheels, did you take them off the Jeep? I thought I had done a good job of cleaning them with the pressure washer but still had HORRIBLE vibrations. I spent an hour removing and replacing the wheels, despite my best efforts there was still a ton of dirt back there and it doesn't take much at all to make it dance all over the road.
