Toe Out
Ideally the front wheels would be held in a striaght-ahead position under all driving conditions by the suspension and steering linkages. However, on front wheel drive vehicles the torque applied to the wheels when accelerating or cruising will make them toe in. Therefore, initially setting the front wheels to toe out will mean that when driven the wheels will tend to be aligned, although not under all driving conditions.
