WHEN TRAVELING AT INTERSTATE HIGHWAY SPEEDS, TRAVELING OVER BRIDGE/OVERPASS EXPANSION JOINTS WILL CAUSE THE FRONT AXLE/STEERING TO SHAKE VIOLENTLY. THIS SEEMS TO SET UP SOME KIND OF WEIRD HARMONIC VIBRATION THAT THE FRONT END CANNOT RECOVER FROM. EVEN AFTER THE ROAD SMOOTHES OUT, FRONT AXLE WILL CONTINUE TO SHAKE VIOLENTLY UNTIL SPEED IS DECREASED TO ABOUT 40MPH. THIS SHAKING IS INCREDIBLY VIOLENT. A LOSS OF CONTROL IS HIGHLY POSSIBLE. TRUCK HAS BEEN TO THE DEALER TWICE AND HAD THE STEERING STABILIZER REPLACED, THIS HAS NOT FIXED THE ISSUE. DEALER HAS NOT BEEN ABLE TO DUPLICATE THE PROBLEM DUE TO THE RANDOM OCCURRENCE AND SPECIFIC ROAD CONDITIONS REQUIRED. I HAVE DRIVEN FORD TRUCKS MY ENTIRE LIFE, THIS IS NOT A NORMAL "CHARACTERISTIC OF VEHICLE". SOMETHING IS WRONG WITH THE DESIGN ON THE FRONT END OF THESE TRUCKS. MY WIFE WILL NOT DRIVE IT. SOMEBODY IS GOING TO GET KILLED. *TR

WHEN TRAVELING AT HIGHWAY SPEEDS A DEFECT OR UNEVEN PORTION IN THE ROADWAY SUCH AS A POTHOLE OR BUMP OR AN EXPANSION JOINT ON AN OVERPASS CAN CAUSE THE FRONT END TO START SHIMMYING UNCONTROLLABLY. THE VEHICLE HAS TO BE SLOWED OR EVEN STOPPED TO MAKE THE SHIMMY STOP WHICH IS A DANGEROUS SITUATION ON A MULTILANE HIGHWAY. THIS HAS OCCURRED TWO TIMES IN THE PAST 3 MONTHS, I MUST STRESS THAT THE SHAKING IS QUITE VIOLENT AND FRIGHTENING. I HAVE BEEN RESEARCHING THIS ON THE INTERNET AND HAVE FOUND THAT MANY PEOPLE HAVE THIS SAME COMPLAINT WITH NO APPARENT FIX FOR THE PROBLEM. IF THIS IS SO THEN I WILL BE TRADING THIS VEHICLE IN FOR ANOTHER BECAUSE THIS IS AN UNACCEPTABLE CONDITION. *TR

THIS MORNING I WAS DRIVING MY 2005 F250 4X4 ABOUT 40 MPH WHEN IT STARTED A DEATH WOBBLE. I HAD TO PULL OVER AND CAME TO A COMPLETE STOP. I LOOKED AT THE TIRES TO DETERMINE IF I LOST A BALANCE WEIGHT. I THEN PROCEEDED ABOUT A HALF MILE AND STOPPED AT A LOCAL STORE. WHEN I LEFT THE DEATH WOBBLE STARTED AGAIN. I KEEP THE TRUCK BELOW 40MPH AND HEADED TO THE STORE WHERE I PURCHASED MY TIRES. IT HAPPENED AGAIN AS I WAS ENTERING THE FREEWAY. I AGAIN HAD TO STOP AND PULL OVER. I KEEP THE TRUCK BELOW 40MPH AND ARRIVED AT THE TIRE STORE WHERE THEY BALANCED THE FRONT TIRES. WHEN I LEFT I AGAIN ENTERED THE FREEWAY AND THE "DEATH WOBBLE" STARTED AGAIN. I KEEP THE TRUCK BELOW 40MPH AND USED SURFACE STREETS TO GET TO THE FORD DEALERSHIP WHERE I PURCHASED MY TRUCK. I WILL HAVE THE RESULTS TOMORROW AFTER OVER $700 WORTH OF REPAIRS. IF I WAS TOWING MY FIFTH WHEEL I THINK THERE WOULD HAVE BEEN A BAD TRAFFIC ACCIDENT. *TR
