TROUBLESHOOTING
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 center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp 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 lamp\
light up.

TIRE AND WHEEL
INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and for the proper inflation pres-
sure.
Cold tire inflation pressure: See page SS−30
(b) Check the tire runout. Tire runout: 3.0 mm (0.118 in.) or less
2. ROTATE TIRES
HINT:
See the illustration for where to rotate each tire.
3. INSPECT WHEEL BALANCE
(a) Check and adjust the Off−the−car balance.
(b) If necessary, check and adjust the On −the−car balance.
Unbalance after adjustment: 13.0 g (0.029 lb) or less
4. CHECK WHEEL BEARING LOOSENESS
Check the no backlash in the bearing shaft direction.
5. CHECK FRONT SUSPENSION FOR LOOSENESS
6. CHECK STEERING LINKAGE FOR LOOSENESS
7. CHECK BALL JOINT FOR LOOSENESS
8. CHECK SHOCK ABSORBER WORKS PROPERLY
Check for oil leaks
Check mounting bushings for wear
Bounce front and rear of the vehicle

FRONT WHEEL ALIGNMENT
INSPECTION
1. MEASURE VEHICLE HEIGHT
Clearance:
A (Follow spring clearance): 36 mm (1.42 in.)
B (Bumper stopper clearance): 104 mm (4.09 in.)
If the clearance of the vehicle is not standard, try to level the ve-
hicle by rocking it down.
If still not correct, check for bad springs or suspension parts.
2. INSTALL CAMBER−CASTER−KINGPIN GAUGE OR ONTO WHEEL ALIGNMENT TESTER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
Camber
Left−right error1°00’ ± 45
45’ or less
Caster Left−right error3°00’ ± 1°
45’ or less
Steering axis inclination13 °00’ ± 45’
Camber, caster and steering axis inclination are not adjustable.
If measurements are not within the specification, inspect the
suspension parts for damaged and/or worn out parts and re-
place them as necessary.
4. INSPECT TOE −IN
To e−in
(total)A+B: 0.2 ° ± 0.2°
C −D: 2 ± 2 mm (0.08 ± 0.08 in.)
If toe− in is not within the specification, adjust by the tie rod end.
5. ADJUST TOE−IN
(a) Loosen the clamp bolts and nuts.
(b) Adjust toe−in to the correct value by turning the tie rod.
HINT:
Make sure that the lengths of the left and right tie rod ends are
the same.
(c) Torque the clamp bolts and nuts. Torque: 37 N·m (375 kgf·cm, 27 ft·lbf)

HINT:
The clamps opening must be positioned at the rear of the tie rod
end face within 60 °±10° from the vehicle axis.
6. INSPECT WHEEL ANGLE
(a) Remove the caps of the knuckle stopper bolts and check the steering angles.
(b) Turn the steering wheel fully, and measure the turning angle.
Inside wheel32°00’ − 35°00’
Outside wheel31 °00’ (Reference)
HINT:
When the steering wheel is fully turned, make sure that the
wheel is not touching the body or brake flexible hose.
If maximum steering angles differ from the standard value, ad-
just the wheel angle with the knuckle stopper bolts.
Torque: 44 N·m (450 kgf·cm, 33 ft·lbf)
If the wheel angle still cannot be adjusted within limits, inspect
and replace damaged or worn steering parts.
