2007 JEEP WRANGLER 4-DR 4X2 Equipment Problems

I AM EXPERIENCING WHAT HAS BECOME KNOWN AS JEEP WOBBLE AND EVEN HAS BEEN CALLED DEATH WOBBLE. DRIVING AT SPEEDS OVER 50 MPH THE VEHICLE BEGINS TO WOBBLE UNCONTROLLABLY AND WILL NOT STOP UNTIL SPEEDS GO BELOW 20 MPH. THIS OCCURS AT TIMES WITHOUT UNSTABLE ROAD CONDITIONS AND IT IS ALMOST ALWAYS OCCURRING WHEN CROSSING A BRIDGE OR ANY WHERE THAT THE ROAD SURFACE CHANGES. JEEP HAS REPLACED THE STEERING STABILIZER AND DAMPENER THREE TIMES WITH NO SUCCESS AND REPLACED THE SHOCKS AS WELL. *TR

WHEN DRIVING ON THE HIGHWAY BETWEEN 50 AND 65 MPH AND HITTING A SLIGHT BUMP OR DIVET IN THE ROAD JEEP WRANGLER JK BEGINS TO VIOLENTLY SHAKE UNCONTROLLABLY UNTIL I AM FORCED TO PULL OVER ONTO THE SHOULDER AND BRING IT UNDER 30MPH. IT HAPPENS AT LEAST ONCE EVERY OTHER DAY, BUT OCCURRED FOUR TIMES TODAY ALONE. AT THE PRESENT TIME I HAVE HAD IT TO THREE DIFFERENT MECHANICS WHERE THE ALIGNMENT HAS BEEN CHECKED FOUR TIMES, THE TIRES HAVE BEEN ROTATED AND ROTATED BACK, A NEW STEERING STABILIZER HAS BEEN INSTALLED ALONG WITH A NEW BUSHING, NEW TRACK BAR AND NEW BALL JOINT. *TR
