Ford 2005 F250 4x4 super duty, violent shaking. On Sat May 30th at approx 11:00 am pacific standard time, I was traveling on the I 280 south freeway with my daughter to a soccer tournament in my 2005 F250 4x4 super duty truck. We were in cruise controll going approx 55 mph. We drove over what I beleive was a large expansion joint on the freeway. Immediatley after we travelled over joint, the vehicle start to violantley shake and vibrate. After a tense moment of complete terror as the vehicle became extreemly difficult to controll and continued to shake violantley we came to a unsafe stop on the freeway. After the complete stop, I immediatley needed to speed up again to prevent being rear ended in the middle of the freeway. The rest of the trip was spent white knuckled traveling well below freeway speeds for fear of another episode of shaking . Every bump in the road was a scary reminder of what might happen again. My daughter is scared to travel in the truck and my wife has demanded that the probelm be addressed immediatley, or "sell the fucking truck" . This is not an isolated incident. Ford Motor Company sent a notice informing me of the probelm. They indicated it could be prevented with proper tire pressure. My tires were well within the range of pressure suggested. I know this becuase I checked them immediatley when I arrived home. This is compleltey unnaceptable and presents a major risk to the driver of these vehicles as well as the surrounding drivers. I almost lost controll of my truck and had flashes of my daughter and I never making it home. There was a parent travelling behind us in a truck. They witnessed the violent shaking and said "i thought your axil was going to come undone and you were going to crash" .This is completley unnacceptable and I will be taking my daughters and my experience to as many forums as possible untill there is a full recall on these trucks. Ford is compeltely aware of the situation, dont let them get away this.
