3. FRONT WHEEL ALIGNMENT
Front wheel alignment is a term given to mean four angle settings in three dimensions camber, kingpin inclination,
toe-in and caster angle. These angle settings are made for the following purposes.
■
Camber
The front wheels are tilted from the vertical as viewed
from the front, the wheels are farther apart at the top than
at the bottom. This inclination is called camber (a).
Camber reduces rolling resistance of the wheels, and
also minimizes bending or twisting of the front axle.

■
Kingpin Angle
The kingpin is tilted from the vertical as viewed from
the front. This angle is called kingpin angle (a). As with
the camber, kingpin inclination reduces rolling resistance
of the wheels, and prevents any shimmy motion of the
steering wheel. It also reduces steering effort.

■
Caster
The kingpin is tilted forward as viewed from the side.
That is, the intersection (a) made by the center line of the
kingpin shaft and the ground is ahead of the intersection
(b) made by the center line of the wheel and ground.
This inclination is called caster (c). Caster helps provide
steering stability. As with the kingpin inclination, caster
reduces steering effort.
