Ca.mber, caster and toe are separate setting. Adjusting one can make a change on the others.
Toe if doing it by string line method is measured at the centers of the front wheels with the steering box centered and the wheels pointed to drive straight ahead.
On my 1940 Ford with Mustang 2 front suspension, someone screwed an alligator and the rack is not centered. The signal cancel does not work evenly left and right. Align.ent shops have not caught this as the steering wheel was installed to the center position. It may be the intermediate shaft installation that is
wrong.
