Wheel Alignment Angles
Econoline 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.
Scheme 1
Camber is the vertical tilt of the wheel (1007) when viewed from the front. Camber can be positive or negative and has a direct effect on tire wear.
Scheme 2
Caster is the deviation from vertical of an imaginary line drawn through the ball joints when viewed from the side. The caster specifications will give the vehicle the best directional stability characteristics when loaded and driven. The caster setting is not related to tire wear.

Scheme 4
The vehicle toe setting
- affects tire wear and directional stability.
- must be checked after adding aftermarket equipment, such as a snowplow or body.

Scheme 6
Dogtracking is the condition in which the rear axle is not square to the chassis. Heavily crowned roads can give the illusion of dogtracking.
