3.2 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 set-

tings are made for the following purposes.

(1) 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.

Camber reduces rolling resistance of the wheels, and

also minimizes bending or twisting of the front axle.

(3) King pin inclination

The kingpin is tilted from the vertical as viewed from

the front. This inclination is called kingpin inclination.

As with the camber, king pin inclination reduces rolling

resistance of the wheels, and prevents any shimmy

motion of the steering wheel. It also reduces steering

effort.

(2) Caster

The kingpin is tilted backward 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 inter-

section (b) made by the center line of the wheel and

ground. This inclination is called caster. Caster helps

provide steering stability. As with the kingpin inclination,

caster reduces steering effort.
