Alignment: Description and Operation
Drift/Pull
Wheel Alignment Angles
The 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.
Drift/Pull
Pull is a tugging sensation, felt by the hands on the steering wheel, that must be overcome to keep the vehicle going straight.
Drift describes what a vehicle with this condition does with hands off the steering wheel.
-
A vehicle-related drift/pull, on a flat road, will cause a consistent deviation from the straight-ahead path and require constant steering input in the
opposite direction to counteract the effect.
-
Drift/pull may be induced by conditions external to the vehicle such as wind or road camber.
