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.

(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.

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).

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
Based on the result of the customer problem analysis, try to reproduce the symptoms. If the problem is that
the transaxle does not shift up, shift down, or the shift point is too high or too low, conduct the following road
test referring to the automatic shift schedule and simulate the problem symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C
(122 to 176°F).
(a) D position test:
Shift into the D position and fully depress the accelerator pedal and check the following points. Check
up±shift operation.
(1) Check up±shift operation.
Check that 1 " 2, 2 " 3, 3 " 4 and 4 " 5th up±shifts take place, and that the shift points conform
to the automatic shift schedule (See page SS±24).
HINT:
5th Gear Up±shift Prohibition Control

Engine coolant temperature is 55 °C (131 °F) or less and vehicle speed is at 51 km/h (32 mph) or less.
4th Gear Up±shift Prohibition Control

Engine coolant temperature is 40 °C (104 °F) or less and vehicle speed is at 45 km/h (28 mph) or less.
5th Gear Lock±up Prohibition Control

Brake pedal is depressed.

Accelerator pedal is released.

Engine coolant temperature is 60 °C (140 °F) or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3, 3 " 4 and 4 " 5th up±shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when up±shifting from 1 " 2, 2 " 3, 3 " 4 and 4 " 5
while driving with the shift lever in the D position, and check while driving in the lock±up condition.
HINT:
The check for the cause of abnormal noise and vibration must be done thoroughly as it could also be due
to loss of balance in the differential, torque converter clutch, etc.
(4) Check kick±down operation.
Check vehicle speeds when the 2nd to 1st, 3rd to 2nd, 4th to 3rd, and 5th to 4th kick±downs take
place while driving with the shift lever in the D position. Confirm that each speed is within the
applicable vehicle speed range indicated in the automatic shift schedule (See page SS±24).
(5) Check abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in the D position (5th gear), at a steady speed (lock±up ON).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
HINT:
If there is a big jump in engine speed, there is no lock±up.
