Toe is a measurement of how much a pair of wheels are turned in or out from a straight-ahead position. You will feel your vehicle ‘pulling’ to one side if the toe alignment is out.

Camber Alignment - Camber is the vertical tilt of the wheel If the camber is out of alignment it will cause the tyre tread to wear excessively on one edge or cause your vehicle to pull to one side.

Camber misalignment may not be adjustable on all vans. If it is out on these vehicles it may indicate that something is worn or bent and should be inspected more closely.

Caster Alignment - Caster alignment is the angle of the steering pivot when viewed from the side of the vehicle.

Caster has little affect on tyre wear, but it affects steering stability. If the caster is out of adjustment, it can cause problems in straight line tracking.

Thrust angle is the direction that the rear wheels are pointing in relation to the centerline of the vehicle.

The vehicle will "dog track" if the thrust angle is not zero and the steering wheel will not be centered.
