TRUCK SHAKING, WAS TOLD TIRE INFLATION WAS NOT BEING MAINTAINED. ALL VALVE STEMS LEAKING SINCE DAY I BOUGHT IT. ONE TIRE HAD FIX A FLAT IN IT WHEN I BOUGHT IT. IT TOOK FORD 6 MONTHS TO REPLACE VALVE STEMS CORRECTLY. AFTER THIS TRUCK STILL SHAKES ON ANY ROUGH ROAD, IF HIT ANY REAL RUFF TRUCK VIOLENT SHAKE HAVE TO STOP TO GET IT TO STOP. NOW SINCE TIRE PRESSURE CAN BE MAINTAINED SINCE VALOVE STEMS FIXED. THEY TELL ME FRONT TIRES NEED REPLACED FROM NOT MAINTAINING TIRE PRESSURES. THAT IS WHY TRUCK SHAKES. THE TRUCK HAS SHAKENOUGH SINCE THE FIRST MONTH I OWNED IT IT MARCH 2018, THIS HAS CAUSED FRONT TIRES TO WERE ON BOTH OUTSIDE EDGES. THE TRUCK SHAKES SO BAD, I HAVE RAN OFF 7 TIMES, RAN TWO OTHER CARS OFF ROAD, AND PULLED OVER FOR SUSPECTED DUI TOLD OFFICER WHAT HAPPENED AND IF I DIDN'T GET IT FIXED HE WRITE ME TICKET DEFECTIVE EQUIPMENT AND DEEM VEHICLE UNSAFE TO OPERATE. ALWAYS IN MOTION, ANY SPEED, ANY RUFF ROAD, EVEN GOING ACROSS BRIGGS ANYTHING THAT IS NOT PERFECT SMOOTH ROAD
