Front Wheel








Before checking front wheel alignment, be sure that vehicle is in an unladen state, i.e. fuel, radiator coolant and engine oil are full and spare tire, jack, hand tools and mats in designated positions.

PRELIMINARY INSPECTION
1. Check tires for wear and improper inflation.








2. Check wheel runout on the inside and outside.

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.
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.
2. If camber, caster or kingpin inclination is not within specification, inspect front suspension parts. Replace damaged or worn out parts.

TOE-IN

WARNING: MAKE SURE THAT NO PERSON IS IN FRONT OF THE VEHICLE BEFORE PUSHING IT.

NOTE: Perform following procedure always on a flat surface.

Measure toe-in using following procedure. If out of specification, inspect and replace any damaged or worn front suspension parts.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (196.9 inch).





3. Put a mark on base line of tread (rear side) of both tires at the same height as hub center. These are measuring points.





4. Measure distance "A" (rear side).
5. Push the vehicle slowly ahead to turn the wheels 180° (1/2 turn).

NOTE: If the wheels have passed 180°, try the above procedure again from the beginning. Never push vehicle backward.

6. Measure distance "B" (front side).







7. Adjust toe-in by varying the length of steering tie-rods.
Standard length "L": 181.0 mm (7.13 inch)
a. Loosen lock nuts.
b. Tighten lock nuts to 37 - 46 Nm (27 - 35 ft. lbs.).

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. Determine the turning angle of full turns. If it is not within specification, check rack stroke.
3. Turn steering wheel to full lock and apply force (at circumference of steering wheel) of 98 - 147 N (22 - 33 lbs.) with engine at idle.

CAUTION: Do not hold the steering wheel on full lock for more than 15 seconds, as very high pressure may build up.

[1]: On power steering models, wheel turning force (at circumference of steering wheel) of 98 - 147 N (22 - 33 lbs.) with engine idle.
