While driving my truck down the highway it will violently shake until I brake below 40 MPH. This occurs when there is a change in surface on the roadway. An example is going over a bridge or rough pavement. It has happened several times in the past year, and most recently last weekend while my wife was with me. We were driving on a major interstate at 65 MPH, maintaining a single lane when the truck went into a "death wobble." The front end shook so violently, it became a safety risk for our lives as well as other drivers. It was extremely difficult to maintain the steering until the truck stopped shaking. My wife no longer feels safe driving the vehicle. In the past, we have taken it to a local mechanic and I was advised they were not able to find an issue. We have purchased new tires and taken them to the Ford dealership to balance and align. We check the tire pressure regulary, and had an alignment done, though the violent shaking is getting worse, rather than better, when it happens. The truck gives no prior warning when this occurs. I don't see any form of recall for this issue, and a forum only advises buying an after market component to fix it. I want the truck fixed correctly, with Ford parts, as my intent was to keep it for several more years.
