FRONT WHEEL ALIGNMENT
INSPECTION
1. MEASURE VEHICLE HEIGHT
Vehicle height:
FrontA - B: 71 mm (2.795 in.)
RearC - D: 51 mm (2.008 in.)
Measuring points:
A: Ground clearance of spindle center
B: Ground clearance of lower suspension arm front bolt center
C: Ground clearance of rear axle shaft center
D: Ground clearance of lower control arm front bolt center
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specified value.
If the vehicle height is not the specified value, try to adjust it by
pushing down on or lifting the body.
2. INSTALL CAMBER-CASTER-KINGPIN GAUGE OR
POSITION VEHICLE ON WHEEL ALIGNMENT TES-
TER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS
INCLINATION
Camber, caster and steering axis inclination:
Camber
Right-left error0°05' ± 45' (0.08° ± 0.75°)
30' (0.5°) or less
Caster
Right-left error2°30' ± 45' (2.5° ± 0.75°)
30' (0.5°) or less
Steering axis inclination
Right-left error12°10' ± 45' (12.17° ± 0.75°)
30' (0.5°) or less
If the steering axis inclination is not within the specified value,
after the camber and caster have been correctly adjusted, re-
check the steering knuckle and front wheel for bearing or loose-
ness.

7. INSPECT AND ADJUST WHEEL ANGLE
(a) Turn the steering wheel fully, and measure the turning
angle.
Wheel turning angle:
Inside wheel36°42' (33°42' - 36°42')
36.7° (33.7° - 36.7°)
Outside wheel: Reference32°36'
32.6°
If the right and left inside wheel angles differ from the specified
value, check the right and left rack end lengths.
(b) When toe-in is normal after inspection, adjust wheel
angle with the knuckle stopper bolt of the lower suspen-
sion arm.
Torque: 44 N´m (450 kgf´cm, 32 ft´lbf)

4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS
6. CHECK BALL JOINT FOR LOOSENESS
7. CHECK SHOCK ABSORBER WORKS PROPERLY
Check that oil leaks
Check the mounting bushings for wear
Bounce front and rear of the vehicle

PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that the transfer shift lever is shifted to the L position.
When switching differential Free e Lock, the indicator light will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated to apply differential
power to the differential, the differential locks and the indicator light lights up.
