Two problems related to front suspension upper ball joint have been reported for the 2005 Ford F-250. The most recently reported issues are listed below.
I was driving down a main st, going about 35 mph. . . When I hit a bump the truck would shake violently and the steering wheel was also shaking violently , I had it diagnosed as the drag link ball joint and an upper ball joint both on the passenger side front. . . I got a letter in the mail from Ford just yesterday about the shimmy/shaking issue, the letter states that it is due to tire pressure in which I believe to be very wrong!!.
Tl-the contact owns a 2005 Ford f250. The contact was driving approximately 65 mph over a bump in the road. The vehicle began to jerk violently causing it to travel uncontrollably across two lanes. The contact was able to regain control and resumed normally. The failure occurred on four separate occasions. The vehicle was taken to an authorized dealer where the upper ball joints were replaced. The failure continued to occur after the repair was performed. The manufacturer notified the owner's the vehicle may experience a potential shimmy and recommended the tires be inflated to the correct pressure to prevent the defect. The manufacturer was made aware of the recurring problem. The approximate failure mileage was 47,000. Js.
