E-350 w/vague steering
My 2001 E-350 XLT w/6.8l V-10 engine has vague steering. When the slope of the road changes, the van moves over about 3 feet and puts you out of your lane. Also, there is quite a bit of bump steer. What I mean is that ofen when you hit a bump, you can feel the steering wheel try to turn. I know there is a service bulletin about this.....does anybody have any ideas??
