1. Mark an ‘A’ at the intersection point of the measured

camber angle value (solid line) and the measured caster

angle value (dotted line).

2. Mark a ‘B’ at the intersection point of the standard camber

angle value (solid line) and the standard caster angle value

(dotted line).

3. The vertical distance between points ‘A’ and ‘B’ represents

the adjustment required at the front cam. The horizontal

distance between points ‘A’ and ‘B’ represents the

adjustment required at the rear cam.

In this example, the front cam would be moved 5

increments to the positive and the rear cam would be

moved 8 increments to the positive.

CAUTION:

Maximum possible adjustment from the center point of the
cams is 9 increments to either side.
