jack, hand tools and mats in designated positions.
lWhen removing each suspension part, check wheel
alignment and adjust if necessary.
lUse Tool when removing or installing brake tubes.
lAlways torque brake lines when installing.

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.
lEnsure that new cotter pins are used, and are correctly fit-
ted.
lRetighten all axle and suspension nuts and bolts to the speci-
fied torque.
Tightening torque:
Refer to FRONT SUSPENSION, FA-26.
lCheck strut (shock absorber) for oil leakage or other dam-
age.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
If ball joint dust cover is cracked or damaged, replace trans-
verse link.

lCheck suspension ball joint end play.
a. Jack up front of vehicle and set the stands.
b. Clamp dial indicator onto transverse link and place indicator
tip on lower edge of brake caliper.
c. Make sure front wheels are straight and brake pedal is
depressed.
d. Place a pry bar between transverse link and inner rim of road
wheel.
e. While raising and releasing pry bar, observe maximum dial
indicator value.
Vertical end play:
0mm(0in)
f. If ball joint vertical end play exists, remove transverse link
and recheck the ball joint. Refer to ªFRONT SUSPENSIONº,
FA-32.
Front Wheel Bearing
lCheck that wheel bearings operate smoothly.
lCheck axial end play.
Axial end play:
0.05 mm (0.0020 in) or less
lIf axial end play is not within specification or wheel bearing
does not turn smoothly, replace wheel bearing assembly.
Refer to ªWheel Hub and Knuckleº, ªFRONT AXLEº, FA-FA-
11 .
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a pre-
liminary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove tire and check wheel runout.
Wheel runout:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work correctly by using the
standard bounce test.
7. Check vehicle posture (Unladen).

CAMBER, CASTER AND KINGPIN INCLINATION
Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, Caster and Kingpin inclination:
Refer to SDS, FA-35.
2. If camber, caster and kingpin inclination are not within
specification, inspect front suspension parts. Replace any
damaged or worn out parts.
TOE-IN
Measure toe-in using following procedure:
WARNING:
lAlways perform following procedure on a flat surface.
lEnsure the way in front of the vehicle is clear before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead for about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires
at the same height as hub center. These are measuring
points.
4. Measure distance ªAº (rear tires).
5. Push the vehicle slowly forwards to rotate the wheels 180
degrees (1/2 turn).
If the wheels have passed 180 degrees, try the above pro-
cedure again from the beginning. Never push vehicle back-
ward.
6. Measure distance ªBº (front tires).
Toe-in (A þ B):
Refer to SDS, FA-35.
7. Adjust toe-in by varying the length of steering tie-rods.
a. Loosen lock nuts.

FRONT WHEEL TURNING ANGLE
1. Set wheels in straight-ahead position. Then move vehicle
forward until front wheels rest on turning radius gauge prop-
erly.
2. Rotate steering wheel all the way right and left; measure
turning angle.
lOn power steering models, turn steering wheel to full lock
and apply force (at circumference of steering wheel) of 98 to
147 N (10 to 15 kg, 22 to 33 lb) with engine at idle.
Do not hold the steering wheel at full lock for more than
15 seconds.
Wheel turning angle (Full turn):
Refer to SDS, FA-35.
