Front
FRONT WHEEL ALIGNMENTBefore checking front wheel alignment, be sure to make a preliminary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
PRELIMINARY INSPECTION
Aluminum wheel
1. Check tires for wear and proper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
a. Remove tire from aluminum wheel and mount on a tire balance machine.
b. Set dial indicator as shown in the illustration.
Wheel runout: (Dial indicator value): Refer to IMAGE ABOVE.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that struts work properly by using the standard bounce test.
7. Check vehicle posture (Unladen).
Steel wheel
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance machine.
b. Set two dial indicators as shown in the illustrations.
c. Set each dial indicator to 0.
d. Rotate wheel, and check dial indicators at several points around the circumference of the wheel.
e. Calculate runout at each point as shown.
Radial runout = (A + B)/2
Lateral runout = (C + D)/2
f. Select maximum positive runout value and the maximum negative value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the maximum value (negative or positive) for total runout.
Wheel runout: Refer to IMAGE ABOVE.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front struts work properly 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 Specifications; Mechanical.
2. If camber, caster and kingpin inclination are not within specification, inspect front suspension parts. Replace damaged or worn out parts.
TOE-IN
Measure toe-in using the following procedure.
WARNING:
- Always perform the following procedure on a flat surface.
- Make 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 tread (rear side) of both tires the same height as hub center. These are measuring point.
4. Measure distance "A" (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 18 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 (A - B): Refer to Specifications; Mechanical.
7. Adjust toe-in by varying the length of steering tie-rods.
a. Loosen lock nuts.
b. Adjust toe-in by screwing tie-rods in or out.
Standard length "L": Refer to IMAGE ABOVE.
c. Tighten lock nuts to specified torque.
37 - 46 Nm (3.8 - 4.7 kg-m, 27 - 35 ft. lbs.)
FRONT WHEEL TURNING ANGLE
1. Set wheels in straight-ahead position. Move vehicle forward until front wheels rest properly on turning radius gauge.
2. Rotate steering wheel all the way right and left; measure turning angle.
- 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 lbs.) with engine at idle.
- Do not hold the steering wheel on full lock for more than 15 seconds.
Wheel turning angle (Full turn): Refer to Specifications; Mechanical.
