What
is Wheel alignment?
A wheel alignment is part of standard automobile maintenance
that consists of adjusting the angles of the wheels so that
they are set to the car maker's specification. The purpose of
these adjustments is maximum tire life and vehicle-travel that
is straight and true when driving along a straight and level
road, although most machines and the technicians who use them
set the alignment to adjust for crowned roads, as well as correct
tracking when driving on turns.
There
are 2 types of angles that adjustments should be made regularly
during the life of an automobile. The first type is called
the Primary Angles and second type is called Secondary Angles.
Within
Primary Angles, there are three adjustment parameters involved
on each axle in order to properly align a vehicle. These adjustments
are camber, caster and toe. It is important to note that on
some cars, there may only be the ability to adjust for one
or two of the parameters.
These
three parameters can be further categorized into front and
rear, so summarily the parameters are:
Front: Caster (Left & Right)
Front: Camber (Left & Right)
Front: Toe (Left, Right & Total)
Rear: Camber (Left & Right)
Rear: Toe (Left, Right & Total)
Rear: Thrust Angle
As
for the Secondary Angles, the adjustment parameters are quite
numerous. They are:
SAI (Left & Right)
Included Angle (Left & Right)
Toe out on turns (Left & Right)
Maximum Turns (Left & Right)
Toe curve change (Left & Right)
Setback (Front & Rear)
Track width difference
Wheel base difference
Front ride height (Left & Right)
Rear ride height (Left & Right)
Frame angle
A camera unit (sometimes called a "head") is attached
to a specially designed clamp which holds on to a wheel. There
are usually four camera units in a wheel alignment system
(A camera unit for each wheel). The camera units communicate
their physical positioning with respect to other camera units
to a central computer which calculates and displays how much
the camber, toe and caster are misaligned.

Total four-wheel alignment is the ultimate wheel alignment service.
Individual read toe is measured, then adjusted to the factory
specifications. This adjustment beings the thrust line of the
rear wheels into coincidence with the vehicle's geometric centreline.
The
front wheels are then aligned to the identical geometric centreline/thrustline.
Total
four-wheel alignment results in all four wheels being parallel
and the steering wheel and steering geometry being centred
as the vehicle moves in a straight line.
