WARNING:
lPlace vehicle on a flat and solid surface.
lPlace chocks at front and rear of rear wheels.
lYou should not remove oil pan until exhaust system and
cooling system have completely cooled off.
Otherwise, you may burn yourself and/or fire may break
out in the fuel line.
lWhen removing front and/or rear engine mounting bolts
or nuts, lift up slightly engine for safety work.
CAUTION:
lIn lifting engine, be careful not to hit against adjacent
parts, especially against accelerator wire casing end,
brake tube and brake master cylinder.
lFor tightening torque, refer to EM-71, MT and PD sec-
tions.
Remove oil pan bolts in order shown.
Installation
1. Install the oil pan gasket with the coated surface facing the
cylinder block and the notch facing the rear of the engine.
2. Tighten all bolts in reverse order of removal. For tightening
torque of oil pan and correct installing direction of drain plug
washer, refer to EM-71.

Front Axle and Front Suspension Parts
Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
lShake each front wheel to check for excessive play.
If looseness is noted, adjust wheel bearing end play, then
check ball joint end play.
lMake sure that the cotter pin is inserted.
lRetighten all nuts and bolts to the specified torque.
: Refer to ``FRONT SUSPENSION'', FA-26.
lCheck front axle and front suspension parts for wear, cracks
or other damage.
lCheck shock absorber for oil leakage and other damage.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel Bearing
lCheck that wheel bearings operate smoothly.
lCheck axial end play.
Axial end play: 0 mm (0 in)
lAdjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.
PRELOAD ADJUSTMENT (2WD)
Adjust wheel bearing preload after wheel bearing has been
replaced or front axle has been reassembled.
1. Before adjustment, thoroughly clean all parts to prevent dirt
entry.
2. Apply multi-purpose grease sparingly to the following parts:
lRubbing surface of spindle
lContact surface between lock washer and outer wheel bear-
ing
lHub cap (as shown at left)
lGrease seal lip
3. Tighten wheel bearing lock nut to the specified torque.
: 34 - 39 N´m (3.5 - 4.0 kg-m, 25 - 29 ft-lb)
4. Turn wheel hub several times in both directions to seat wheel
bearing correctly.
5. Again tighten wheel bearing lock nut to the specified torque.
: 34 - 39 N´m (3.5 - 4.0 kg-m, 25 - 29 ft-lb)

6. Turn wheel bearing lock nut back 45 degrees.
7. Fit adjusting cap and new cotter pin. Align cotter pin slot by
loosening nut 15 degrees or less.
8. Measure wheel bearing preload and axial end play.
Axial end play: 0 mm (0 in)
Wheel bearing preload
(As measured at wheel hub bolt):
New grease seal
9.8 - 28.4 N (1.0 - 2.9 kg, 2.2 - 6.4 lb)
Used grease seal
9.8 - 23.5 N (1.0 - 2.4 kg, 2.2 - 5.3 lb)
Repeat above procedures until correct bearing preload is
obtained.
9. Spread cotter pin.
10. Install hub cap.
PRELOAD ADJUSTMENT (4WD)
Adjust wheel bearing preload after wheel bearing has been
replaced or front axle has been reassembled.
Adjust wheel bearing preload as follows:
1. Before adjustment, thoroughly clean all parts to prevent dirt
entry.
2. Apply multi-purpose grease sparingly to the following parts:
lThreaded portion of spindle
lContact surface between wheel bearing washer and outer
wheel bearing
lGrease seal lip
lWheel hub (as shown at left)
3. Tighten wheel bearing lock nut with Tool.
: 78 - 98 N´m (8 - 10 kg-m, 58 - 72 ft-lb)
4. Turn wheel hub several times in both directions.
5. Loosen wheel bearing lock nut so that torque becomes 0 N´m
(0 kg-m, 0 ft-lb).
6. Retighten wheel bearing lock nut with Tool.
: 0.5 - 1.5 N´m (0.05 - 0.15 kg-m, 4.3 - 13.0 in-lb)

TOE-IN
Measure toe-in using the following procedure.
WARNING:
lAlways perform the following procedure on a flat sur-
face.
lMake sure that no one is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires
at the same height of hub center. This mark is a measuring
point.
4. Measure distance ``A'' (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
lIf the wheels have rotated more than 180 degrees (1/2
turn), try the above procedure again from the beginning.
Never push vehicle backward.
6. Measure distance ``B'' (front side).
Total toe-in:
Refer to SDS, FA-36.
7. Adjust toe-in by varying the length of both steering tie-rods.
a. Loosen clamp bolts or lock nuts.
b. Adjust toe-in by turning both the left and right tie-rod tubes
equal amounts.
Make sure that the tie-rod bars are screwed into the tie-rod
tube more than 35 mm (1.38 in).
Make sure that the tie-rods are the same length.
Standard length (A = B):
2WD
343.9 mm (13.54 in)
4WD
297.6 mm (11.72 in)
c. Tighten clamp bolts or lock nuts, then torque them.

ground.
Preparation for Disassembly
CHECKING DIFFERENTIAL TORQUE
Measure differential torque with Tools.
If it is not within the specifications, inspect components of limited
slip differential.
Differential torque:
88 - 108 N´m
(9.0 - 11.0 kg-m, 65 - 80 ft-lb)
Tool numbers:
VAKV38105110
VBKV38105120
Disassembly
1. Remove couple bolts using a press.
Tool number: ST33081000
2. Separate differential cases A and B.
Draw out component parts (discs and plates, etc.).
Put marks on differential cases so that they can be rein-
stalled in their original positions.
