(1) POSSIBLY TRIGGERED BY A MINOR BUMP IN THE ROAD (2) SEVERE STEERING AND/OR FRONT AXLE OSCILLATION RESULTING IN LOSS OF VEHICLE CONTROL. THE OSCILLATION WAS MUCH MORE SEVERE THAN THE COMMON "DEATH WOBBLE" FROM OUT OF BALANCE OR OUT OF ROUND TIRES, AND APPEARED TO INVOLVE NOT JUST THE FRONT TIRES, BUT THE ENTIRE FRONT AXLE. THIS HAS HAPPENED TWICE, ONCE BEFORE THE FIRST SET OF REPAIRS, ONCE AFTER THE FIRST SET OF REPAIRS. VEHICLE RAN COMPLETELY OFF THE HIGHWAY BOTH TIMES. (3) THE FIRST TIME, THE STEERING BOX BROKE AS A RESULT OF THE VIOLENCE OF THE STEERING OSCILLATIONS, SO THE STEERING BOX WAS REPLACED. AFTER THE SECOND TIME THE VEHICLE RAN OFF THE ROAD, THE VEHICLE'S ALIGNMENT WAS CHECKED, THE TIRES WERE ROTATED, THE TIRE PRESSURE WAS ADJUSTED. THE DEALER PERFORMED ALL THE STEPS OUTLINED IN A TECHNICAL SERVICE BULLETIN, BUT SAID THAT THEY FOUND NOTHING WRONG THAT WOULD ACCOUNT FOR THE PROBLEM. NOW, OUR DRIVERS ARE AFRAID TO DRIVE THIS TRUCK AGAIN. THIS IS A FLEET VEHICLE, AND AFTER SOME INVESTIGATION WE HAVE LEARNED THAT WE HAVE AT LEAST FIVE OTHER TRUCKS OF THIS DESIGN (2005 AND 2006 FORD 4X4 F-250) THAT HAVE EXHIBITED SIMILAR PROBLEMS. WE HAVE BEEN TOLD THAT AN AFTERMARKET STEERING STABILIZER (THAT FORD WILL NEITHER SUPPLY OR STAND BEHIND) WILL FIX THE PROBLEM, BUT WE DON'T BELIEVE IT. IT MIGHT REDUCE THE SYMPTOMS, BUT WE ARE CONVINCED THE PROBLEM IS DESIGN RELATED. THE FRONT END DESIGN ON THESE TRUCKS WAS CHANGED IN LATE 2004, AND THE OSCILLATION PROBLEM APPEARS TO BE RELATED TO A LACK OF LATERAL (BY THAT I MEAN SIDE TO SIDE) STIFFNESS IN THE SUSPENSION. *NM

DRIVING 2-LANE HIGHWAY 55-70 MPH WHEN CHANGE IN ROAD SURFACE (BUMP, FROST HEAVE, ROAD BED SURFACE MATERIAL CHANGE) CAUSED FRONT END TO SHAKE VIOLENTLY, NEARLY CAUSING LOSS OF CONTROL. ONLY WAY TO STOP SHAKING WAS TO SUDDENLY DECREASE SPEED TO APPROXIMATELY 35-50 MPH IN TRAFFIC ON RAIN-SLICK ROADWAY. THIS OCCURRED 4 TIMES IN COURSE OF 350 MILE TRIP, EACH OCCURRANCE BECOMING MORE VIOLENT IN NATURE AND REQUIRING MORE EFFORT TO MAINTAIN CONTROL. LAST OCCURRANCE WAS AS OPERATOR WAS PASSING 18-WHEELER...AS I PULLED ALONG SIDE, VEHICLE BEGAN TO SHAKE VIOLENTLY. AS OPERATOR FINISHED PASSING AND RETURNED TO LANE OF TRAVEL, HAD TO BRAKE SUDDENLY TO REGAIN CONTROL, NEARLY CAUSING SKID ON RAIN-SLICK ROAD AND ALMOST CAUSING FOLLOWING VEHICLES TO TAKE EXTREME MEASURE TO AVOID COLLISION. *JB

WHEN TRAVELING AT 70+ MPH ON THE INTERSTATE AND ENCOUNTERING A CHANGE IN ROAD SURFACE SUCH AS AN OVERPASS OR CULVERT BRIDGE THE STEERING WHEEL SEVERELY JERKS BACK AND FORTH. THE ONLY WAY TO REMEDY THE PROBLEM IS TO SLOW TO ABOUT 45 MPH OR LESS (CAN BE DIFFICULT IN TRAFFIC). I HAVE HAD THE WHEELS ROTATED, BALANCED AND I ALWAYS CHECK THE AIR PRESSURE BEFORE A TRIP. I REPLACED THE FACTORY STABILIZER WITH A BEEFED UP SINGLE DAMPENER AFTERMARKET BECAUSE THE FACTORY DAMPENER LOST ALL THE OIL THE SECOND TIME IT HAPPENED. IT HAS NOT REMEDIED THE PROBLEM! THIS IS AN ACCIDENT WAITING TO HAPPEN, NOW I CANNOT EVEN DRIVE THE SPEED LIMIT ON OUR INTERSTATE FOR FEAR OF LOSING CONTROL! *JB

WHILE TRAVELING ON THE HIGHWAY AT 75 MPH AS I HIT BUMPS IN THE ROADWAY THE VEHICLE FEELS LIKE THE FRONT WHEELS ARE HOPPING. ON 5 OCCASIONS I WAS TRAVELING OVER AN OVERPASS WERE THERE IS A SEEM FROM THE 2 DIFFERENT ROADWAY SURFACES. THE VEHICLE SHOOK VIOLENTLY FEELING AS IF THE TRUCK WAS GOING TO LOSE CONTROL. THE VEHICLE WAS ALLOWED TO SLOW AND AT ABOUT 55 MPH THE SHAKING WOULD STOP. AT SLOWER SPEEDS THE SAME VIBRATION IS FELT BUT AT A MUCH LESS MAGNITUDE AND SEVERITY. THIS LOSS OF CONTROL AS WELL AS THE SLOWING IN LANES OF TRAFFIC COULD CAUSE SERIOUS LOSS OF CONTROL AND CAUSE OF CRASH. DEALER, BORMAN AUTOPLEX LAS CRUCES,NM, HAD NO ANSWER AS THE VIOLENT SHAKING WAS NOT DUPLICATED NEAR OUR CITY. ( ALL OCCURRENCES HAPPENED ON TRIPS). DEALER STATED NOTHING WAS WRONG AND THAT SOME PEOPLE SAY THAT PUTTING SANDBAGS IN THE BACK OF THE TRUCK HELPED. THEY ALSO SAID THAT IF THE TIRES WERE KEPT AT THE 75 PSI THAT IT WOULD STOP. NOTHING HAS HELPED AND IT IS STILL NOT RESOLVED. *JB

FLEET OF 7 TRUCKS ALL EXPERIENCE SAME, SOME WORSE THAN OTHERS. DEALER HAS DONE ALL POSSIBLE TO REMEDY, INCLUDING AFTERMARKET HEAVIER DUTY FRONT STEERING STABILIZER (AT OUR EXPENSE). INCIDENT DATE IS LAST DATE IT OCCURRED TO MY CRUISER TRUCK. IT HAPPENS EVERY TIME A BUMP IN THE HIGHWAY IS ENCOUNTERED WITH EVERY TRUCK OUR DEPARTMENT BOUGHT FOR USE AS LAW ENFORCEMENT VEHICLES. THE MAGNITUDE OF THE WOBBLE IS DEPENDANT ON THE SPECIFIC TRUCK AND THE SPEED TRAVELED. REALIZE THAT AS LAW ENFORCEMENT RESPONSE VEHICLES, OFTEN THIS INVOLVES VERY HIGH SPEED. THE HIGHER THE SPEED, THE WORSE THE PROBLEM.
