I have a 2000 f250 ec. I am having a problem with my steering. What will happen is when I am driving the steering wheel will jerk in my hand and the truck will feel like it wants to turn to which ever side the wheel jerks. It's not something that is a constant ,but as I'm driving it will happen every few minutes. If the wheel doesn't jerk I can feel it pulling to one side or the other. I just had the brakes done and we thought it might be the brakes, but after three trips to the mechanic we are sure now that it isn't brakes. This all started when during a torrential rain I drove into a large puddle that I never saw until I hit it. Two days later the problem started. The ball joints and tie rods were done last year by the original owner. Steering stabilizer looks to have been on for a few years. Anyone have any ideas ? Thanks.
