INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel free play (See page SR±9).
(b) Check the steering linkage for looseness or damage.
Check that:

Tie rod ends do not have excessive play.

Dust seals are not damaged.

Boot clamps are not loose.
2. INSPECT SRS AIRBAG (See page RS±3)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leaks.
If leakage is found, check the cause and repair.
4. 4WD:
INSPECT DRIVE SHAFT BOOTS
Inspect the drive shaft boots for clamp looseness, grease leak-
age or damage.
5. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(b) Inspect the dust cover for damage.
6. 2WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION
AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.
Transmission fluid (A/T): See page

(b) Differential:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
Differential oil: See page SA±129
7. 4WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION,
TRANSFER AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.
Transmission fluid (A/T): See page DI±524
(b) Transfer:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
Transfer oil: See page TR±4
(c) Differential:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil
until it reaches the bottom of the filler hole.

8. REPLACE TRANSFER AND DIFFERENTIAL OIL
(a) Transfer:
Remove the transfer cover.
(b) Remove the drain plug and drain the oil.
(c) Reinstall the drain plug securely.
(d) Add new oil until it reaches the bottom of the filler hole.
Transfer oil: See page TR±4
Front differential oil: See page SA-38
Rear differential oil: See page SA±129
9. REPLACE AUTOMATIC TRANSMISSION FLUID
(a) Remove the drain plug and drain the fluid.
(b) Reinstall the drain plug securely.
(c) With the engine OFF, add new fluid through the dipstick
tube.
Transmission fluid (A/T): See page DI±524
(d) Start the engine and shift the selector into all positions
from ºPº through ºLº and then shift into ºPº.
(e) With the engine idling, check the fluid level.
Add fluid up to the ºCOOLº level on the dipstick.
(f) Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.
10. RECOAT FRONT WHEEL BEARINGS AND THRUST
BUSH
(a) Recoat the front wheel bearing with grease (See page
SA±28).
