NHTSA Complaint #11280419 — 2017 FORD F-350

2017 FORD 350 SRW/CREW CAB/LONG BED/DIESEL, 31K MILES, STEER/BUMP RESONANCE / DEATH WOBBLE AS SOME REFER TO IT AS, HAPPENED FOR THE FIRST TIME ABOUT 2K MILES AGO. I WAS ON A STRETCH OF HIGHWAY THAT HAD A VERY WEIRD RIPPLE WHICH TRIGGERED THE FIRST INCIDENT, I THOUGHT IT WAS AN ANOMALY DUE TO CONDITIONS AND DIDN'T THINK ANYTHING MORE. SINCE THEN I HAVE NOTICED A SLIGHT VIBRATION IN THE STEERING WHEEL THAT IS PARTICULARLY PRONOUNCED WHEN IN A SLIGHT LEFT HIGHWAY TURN (UNLOADING THE STEERING DAMPER I ASSUME). WHILE TRAVELLING STRAIGHT AND LEVEL I WENT OVER A BRIDGE TRANSITION AND WENT INTO A STEER/BUMP RESONANCE WHICH FORCED ME TO THE SHOULDER AND SLOWING TO 30 MPH OR SO BEFORE IT DIMINISHED. THIS CAN BE DISTURBING ON AN EMPTY ROAD AND DOWNRIGHT DANGEROUS ON A BUSY ONE. I'M JUST LUCKY THAT IT WAS A RELATIVELY LOW TRAFFIC ENVIRONMENT DURING THE MOST CURRENT INCIDENT.
