steering problems 65 mustang

[Jeff65]

Bump steer occurs because the pivot point of the steering arms (outer tie rods) moves in a different arc from the suspension arms. What happens is the suspension parts "pull" or "push" the steering arms as they move. Having this property has to do with how the steering & suspension are designed. Early Mustangs have this property. It is minimized when the suspension is in the center of its travel and the arcs are about the same. In extremes (high or low) you can expect it unless you've compensated for it. I believe it will go away when you install the V8 and the front end drops down where it should be.
