I HAVE A 2015 F 250 SUPERDUTY, ORIGINAL OWNER, THAT I AM NOW EXPREIENCE WHAT IS REFERED TO AS A "DEATH WOBBLE.' THIS HAS HAPPENED TO ME FOUR TIMES OVER THE PAST THREE MONTHS. EACH TIME I WAS DRIVING AT ABOUT 70 MPH, EITHER ON A CONCRETE FREEWAY, OR ON AN ASHPALT HIGHWAY, HIT A SMALL BUMP IN THE ROAD, THEN THE TRUCK BOUNCES AROUND. YOU DO NOT HAVE CONTROL OF THE VEHICLE, STEERING INPUT CAUSES IT TO INCREASE THE WOBBLING AND BOUNCING. EACH TIME THE WOBBLE DID NOT STOP UNTIL I WAS BELOW 40 MPH AND BRAKING. ONE TIME I HAD AN EMPTY 16 FOOT FLAT BED TRAILER, WHICH ALMOST CAUSED THE TRAILER TO FLIP. THE THREE OTHER TIMES NO TRAILER. EACH TIME I FELT HEPLLESS IN CONTROLING THE VEHICLE AND SCARRNG THE *^%^*& OUT OF ME.IN RESEARCHING THE INTERNET THIS ISSUE HAS BEEN A PROBLEM FOR SOME TIME AND THERE HAS BEEN NO RECALL. WHY HAS THERE BEEN NO RECAL ON THIS ISSUE?
