If the steering axis inclination is not within the specified values,
after the camber and caster have been correctly adjusted, re-
check the steering knuckle and front wheel bearing for loose-
ness.
4. ADJUST CAMBER AND CASTER
(a) Loosen the front and/or rear adjusting cam set bolts.
(b) Adjust the camber and caster by turning the front and/or
rear adjusting cams (See adjustment chart).
HINT:
Try to adjust the camber and caster to the center of the specified
values.

(c) How to read the adjustment chart (Example).
(1) Find the applicable wheel alignment standard value
for the particular model.
(2) Mark the selected standard value on the adjustment
chart.
Example:
Camber: 0°08' (0.13°)
Caster: 2°59' (2.98°)
(3) Measure the present wheel alignment value with
the vehicle unloaded.
(4) Mark the measured present value on the adjust-
ment chart.
Example:
Camber: 0°20' (0.33°)
Caster: 2°59' (2.98°)
(5) As shown in the example chart, read the distance
from the measured value to the standard value, and
adjust the front and/or rear adjusting cams accord-
ingly.
Amount to turn the adjusting cams (by graduation):
Example:
Front cam: 1.4 (+ direction)
Rear cam: 1.3 (+ direction)
