Due to the above adjustments, Camber variations will be equally distributed in the
vehicle (in motion) at any point of time. The process of bringing the Camber to average
Runout position is called Runout compensation.
The equipment does the Runout compensation automatically without the knowledge of
technician.
In Jacked up Runout method, the Technician has to simply rotate the wheel as guided
by equipment for 90°and drop the wheel on Rotary plate.
In Roll-on Runout method, the wheel has to be rotated only at 90° backward from the
parked position.
Rest of the calculations is automatic and average Runout compensation is achieved.
Above theory is also applicable for achieving the average Runout compensation in Toe
setting.
Once Camber & Toe Runout are compensated, best results can be expected in terms
of wheel alignment.

INCLUDED ANGLE
Fig. 19
INCLUDED ANGLE
is the angle formed between the Kingpin inclination and the
Camber. Included angle is not directly measurable. To determine the Included angle,
Kingpin Inclination is added to the Camber. If the Camber is negative, then the
Included angle will be less than the Kingpin Inclination. If the Camber is positive, it will
be greater. The Included angle must be the same from side to side even if the Camber
is different. If it is not the same, then something is bent, most likely the steering
knuckles.
