Front Axle and Front Suspension Parts
Check front axle and front suspension parts for excessive play,
cracks, wear and other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspensions nuts and bolts to the speci-
®ed torque.
Tightening torque:
Refer to FRONT SUSPENSION (FA-24).
+Check front axle and front suspension parts for wear, cracks
and other damage.
+Check shock absorber for oil leakage and other damage.
+Check knuckle ¯ange for grease leakage and knuckle ¯ange
grease seal for cracks and other damage.
Front Wheel Bearing
+Check that wheel bearings operate smoothly.
+Check axial end play.
Axial end play:
0mm(0in)
+Adjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.

TOE-IN
Measure toe-in using the following procedure.
WARNING:
+Always perform the following procedure on a ¯at surface.
+Make sure that no person 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).
If 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-27).
7. Adjust toe-in by varying the length of steering tie-rod.
(1) Loosen lock nuts.
(2) Adjust toe-in by screwing tie-rod in and out.
Make sure both tie-rods are the same length.
(3) Tighten lock nuts to speci®ed torque.
Lock nut tightening torque:
Refer to ST section (``POWER STEERING GEAR
AND LINKAGE'').
FRONT WHEEL TURNING ANGLE
Turning angle is set by stroke length of steering gear rack and
cannot be adjusted.
1. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Do not hold the steering wheel on full lock for more than 15
seconds.
Wheel turning angle (Full turn):
Refer to SDS (FA-27).
3. Adjust by stopper bolt if necessary.
