BALANCING WHEELSNJSU0042Preliminary InspectionNJSU0042S011. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage.
If deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown in the illustration.
Wheel runout (Dial indicator value):
Refer to SDS, SU-15.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly.
7. Check vehicle posture (Unladen).

TIRE ROTATIONNJSU0043+Do not include the T-type spare tire when rotating the tires.
Wheel nuts:
: 98 - 118 N´m (10.0 - 12.0 kg-m, 72 - 87 ft-lb)
FRONT WHEEL ALIGNMENTNJSU0045Before checking front wheel alignment, be sure to make a prelimi-
nary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
SRA096A
Camber, Caster and Kingpin InclinationNJSU0045S01Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, caster and kingpin inclination:
Refer to SDS, SU-14.
2. If camber, caster or kingpin inclination is not within
specification, inspect front suspension parts. Replace dam-
aged or worn out parts.

Toe-inNJSU0045S02Measure toe-in using the following procedure.
WARNING:
+Always perform the following procedure on a flat surface.
+Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tires at the
same height as hub center. These are measuring points.
SFA234AC
4. Measure distance ªAº (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance ªBº (front side).
Total toe-in:
Refer to SDS, SU-14.
SFA486A
7. Adjust toe-in by varying the length of steering tie-rods.
a. Loosen lock nuts.
b. Adjust toe-in by screwing tie-rods in and out.
Standard length ªLº:
Refer to ST-35, ªSDSº.
c. Tighten lock nuts to specified torque.
Lock nut tightening torque:
Refer to ST-16, ªPOWER STEERING GEAR AND
LINKAGEº.

Front Wheel Turning AngleNJSU0045S031. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Do not hold the steering wheel on full lock for more than
15 seconds.
Wheel turning angle (Full turn):
Refer to SDS, SU-14.
