NHTSA Complaint #710296 — 1992 FORD EXPLORER

SEVERE VIBRATION PROBLEM BETWEEN 55 AND 65 MPH. I HAVE OWNED TWO 1992 EXPLORERS AND BOTH HAVE THIS PROBLEM. DEALER AND TIRE MANUFACTURERS DENY KNOWLEDGE OF ANY SUCH PROBLEM. I SEE THERE ARE MULTIPLE COMPLAINTS IN YOUR DATA BASE THAT IDENTIFY THE SAME PROBLEM. LOCAL FORD DEALER HAS SAID THERE IS NO SERVICE BULLETIN ON THIS PROBLEM, HOWEVER, I SEE YOUR DATA BASE LISTS SB033695 AS A LIKELY BULLETIN THAT ADDRESSES THIS ISSUE. HOW CAN I GET A COPY OF THE BULLETIN IF FORD DENIES IT EXISTS? THIS VIBRATION PROBLEM SHOWED UP AT JUST OVER 65,000 MILES ON THE VEHICLE AND I HAVE DONE SEVERAL WHEEL BALANCING EFFORTS, BEARING AND ROTOR REPLACEMENTS TO CORRECT. ADDITIONALLY, I SUSPECT THE VIBRATION PROBLEM COULD BE RELATED TO SERVICE BULLETIN SB037583 WHICH DESCRIBES "VEHICLE OPERATION THAT GENERATES HIGH EXHAUST MAY CAUSE THE RADIUS ARM INSULATOR TO DETERIORATE--I HAVE OBSERVED SUCH DETERIORATION ON MY VEHICLE AND MAY BE THE SOURCE OF REDUCED STIFFNESS OR DAMPING THAT CONTRIBUTES TO WHEEL CRITICAL SPEED VIBRATION RESPONSE. PLEASE PROVIDE INFORMATION ON HOW TO GET A COPY OF THIS SERVICE BULLETIN TOO. THANK YOU FOR YOUR TIME. I LOOK FORWARD TO YOUR RESPONSE.
