3. The distance between these two points
should be approximately 1/8 inch (3 mm). If
not, the steering stop screws must be
readjusted.
4. Check the stroke of the steering stabilizer
cylinder (damper). It should not exceed
12.59 inches (320 mm).
5. The steering stopper screw must be in
contact before the steering stabilizer
reaches the end of the stroke.
6. This must be done for a full left turn.
7. If readjustment is required:
a. Remove the swivel stop screw.
b. Add to the stop screw the required
number of washers to obtain the
proper measure, tighten the stop

15.1.8 Front Wheel Camber
Wheel camber is the number of degrees the top
of the wheel tilts outward (positive) or inward
(negative) from a vertical angle (Figure 38).
FIGURE 38: CAMBER
The camber angle is not adjustable. Camber
variations may be caused by wear at the wheel
bearings, steering knuckle pins or by a bent
knuckle or sagging axle center. Steering effort is
affected by improper camber, and uneven tire
wear will result. Excessive positive camber
causes an irregular wear of tire at the outer
shoulder and excessive negative camber causes
wear at the inner shoulder.
15.2 CAMBER CHECK
1. Use an alignment machine to check the
camber angle.
2. If camber reading is not in the
specifications, adjust the wheel bearings
and repeat the check. If the reading is still
not within specifications, verify the steering
knuckle pins and axle center.
3. See instructions in “DANA SPICER
Maintenance Manual Model NDS and
Maintenance Manual NDS Axles”.
4. Check the wheel lateral distortion as
instructed in Section 13, ‘’Wheels, Hubs
and Tires’’ under heading, ‘’Checking for
Distorted Wheel on Vehicle’’. If distortion is
excessive, straighten or replace wheel(s).
