NHTSA Complaint #11550227 — 2016 FORD F-250

My truck has developed what is colloquially called a death wobble. The truck shakes wildly and aggressively when hitting a bump. It happens most frequently when crossing the transition from roadway to bridge. But it can occure from a bump in the roadway. When it occurs I have no control. I have paid to replace the steering damper That did not alleviate the problem. My truck is a 2016 Ford F-250 Super Duty. This wobble has occurred several times. To date, except for the initial occurrence, this has only occurred on interstate highways at regular highway sppeds depending on the particular state speed limit. The initial event occurred on a state highway in Colorado while negotiaing a sweeping left curve. Thereafter, it has only occurred on interstate highways. Speeds have alwasy been 60mph or above, depending on speed limits and trafic conditions.
