I guess my point is it would appear much of the bump steer is from bad design. Lower A arm should be close to level as possible at ride height. The upper A arm should be parallel with the lower. There should be an imaginary line between the inside upper A arm pivot point, the steering rack inside tie rod end pivot point, and the lower A arm inside pivot point. This will allow for a constant arch as the suspension moves up and down. One common mistake is the wrong length steering rack that is not in line with the other A arm pivot points or a rack that was shifted to one side for the steering shaft to clear the frame. When it is not in line it pulls the tire in and out as it arch’s through the travel. Obviously there are other causes, but this is a big one.
