Caster Adjustment

The caster angle is the angle between
the vertical and the steering knuckle
pivot axis in a the longitudinal axis.
A higher caster angle improves direc-
tional stability but increases steering
effort. For best controls in bumpy
trails, select a high caster angle.

A lower caster angle gives a quicker
steering response but less directional
stability. For best maneuverability on
trails with low speed tight turns, select
a low caster angle.
The caster angle is factory preset at 8°.
Adjustment can be varied from 3° to
10°.
The caster angle variation is obtained
by moving shims in front or behind the
upper suspension arms bearing hous-
ings.
WARNING
Adjust LH and RH caster angles to
the same value.
NOTE: The caster, camber and steer-
ing alignment (toe) are interrelated.
Start from the factory settings and
customize each adjustment one at a
time. Correct the other adjustments if
needed.
To adjust, proceed as follows on both
sides:
1. Remove wheel, see procedure in
MAINTENANCE INFORMA-
the
TION
section.
2. Keeping the vehicle on jack stands,
remove the bolts retaining the upper
suspension arm to the frame.
