NHTSA Complaint #10534069 — 2011 FORD F-250

WAS GOING OVER A BRIDGE THAT HAD UNEVEN PAVEMENT WITH A SLIGHT BANK TO THE LEFT AND THE STEERING AND ENTIRE VEHICLE BEGAN TO SHAKE UNCONTROLLABLY AND PUT THE VEHICLE INTO THE NEARBY FIELD AFTER RUNNING OFF THE ROAD. I CONTACTED FORD DEALERSHIP AND WAS INFORMED TO CHECK TIRE AIR PRESSURE (AIR PRESSURE WAS FINE-STOCK TIRES AND RIMS). FRONT STEERING STABILIZER WAS CHECKED AND THAT WAS FINE. TRACK BAR AND TIE ROD CHECKED AND THOSE TOO WERE FINE. A LOCAL FOUR WHEEL DRIVE SHOP INFORMED ME THAT THEY ARE QUITE AWARE OF THIS PROBLEM AND AT 31000 MILES THEY RECOMMENDED CHANGING THE TIE ROD, DUAL STEERING STABILIZERS, AND ANOTHER ALIGNMENT. MOST OFF ROAD DEALERS ARE AWARE OF THIS PROBLEM AND EVEN SAY TO ADJUST THE CASTER TO A POSITIVE 4 TO CORRECT. AS SEEN ON THE INTERNET, THIS BEGAN AROUND 2005 WITH STRAIGHT AXLE AND COIL SUSPENSION. FORD MUST RECTIFY THIS PROBLEM! *TR
