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
