While driving the Jeep Wrangler on a smooth pavement @ 55mph the steering wheel began shaking violently and the entire vehicle was shaking. It seemed as if both front wheels were loose. I immediately braked, pulled off the highway to a complete stop. Upon finding nothing loose I proceeded down the highway, upon reaching 55mph the vehicle repeated the shaking. I have replaced the track bar, steering dampener, front brake rotors, brake pads, new tires, wheels checked with calipers,and 2 alignments. I still cannot exceed 55mph without the violent shaking.
