Wheel Alignment Angles

F-Super Duty vehicle caster and camber correction requirements are factory determined. Adjusters are available to correct a caster/camber measurement that does not meet specification. Before changing the production caster/camber adjuster, thoroughly inspect the suspension system to locate worn or damaged components that may have caused the setting to change.

Positive Toe (Toe In)





Negative Toe (Toe Out)





Incorrect Thrust Angle (Dogtracking)









Incorrect thrust angle (dogtracking) is the condition in which the rear axle is not square to the chassis. Heavily crowned roads can give the illusion of dogtracking.

The vehicle toe setting:

- affects tire wear and directional stability.
- must be checked after adding aftermarket equipment, such as a snowplow or body.

When the wheels are turned in toward the front of the vehicle, the toe is positive (+) (toe in). When the wheels are turned out toward the front of the vehicle, the toe is negative (-) (toe out). This is measured in degrees, from side-to-side, and totaled.
