Alignment: Service and Repair

WHEEL ALIGNMENT STANDARD

1. FRONT WHEEL ALIGNMENT

NOTICE:
- When the wheel alignment is performed, or a suspension related part is removed and installed/replaced, make sure to the cable from the negative (-) battery terminal for 2 seconds or more after finishing, and then reconnect the cable and perform initialization.
- If the vehicle is equipped with a VSC system, when the wheel alignment is performed, or a suspension related part is removed and installed/replaced, always perform the following initialization so that the system can function normally: (1) Disconnect the cable from the negative (-) battery terminal for 2 seconds or more and then reconnect it; then (2) perform the yaw rate sensor zero point calibration and test mode inspection.
- If the vehicle has an object recognition camera, after the wheel alignment is performed, always adjust the object recognition camera.

a. MEASURE VEHICLE HEIGHT

1. Bounce the vehicle at the corners up and down to stabilize the suspension and inspect the vehicle height.

Measuring points:

A
Ground clearance of front wheel center

B
Ground clearance of head center of bolt used to install the front No. 1 suspension lower arm to the front suspension member

C
Ground clearance of rear wheel center

D
Ground clearance of pit center of the attachment rear suspension arm

NOTICE:
- The standard value shown here is a value that is used for adjusting the wheel alignment and does not indicate the height of an actual vehicle.
- Before inspecting the wheel alignment, adjust the vehicle height to the specified value.

If the vehicle height is not as specified, adjust the height by pressing down on the vehicle several times to stabilize the suspension.

b. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

1. Put the front wheels on the center of the alignment tester.
2. Remove the center ornament.
3. Install the camber-caster-steering axis inclination gauge at the center of the axle hub or drive shaft.
4. Inspect the camber, caster and steering axis inclination.

NOTICE:
- Inspect while the vehicle is empty.
- The maximum tolerance of right and left difference for the camber is 30' or less.
- The maximum tolerance of right and left difference for the caster is 45' or less.

5. Remove the camber-caster-steering axis inclination gauge and attachment.
6. Install the center ornament.

If the caster and steering axis inclinations are not within the specified values, after the camber has been correctly adjusted, recheck the suspension parts for damaged and/or worn out parts.

c. INSPECT TOE-IN
1. Bounce the vehicle up and down at the corners to stabilize the suspension and inspect toe-in.

If toe-in is not within the specified range, adjust it at the rack ends.

d. INSPECT WHEEL ANGLE
1. Turn the steering wheel fully to the left and right and measure the turning angle.

If the right and left inside wheel angles differ from the specified range, check the right and left rack end lengths.

2. REAR WHEEL ALIGNMENT
a. MEASURE VEHICLE HEIGHT

1. Bounce the vehicle at the corners up and down to stabilize the suspension and inspect the vehicle height.

If the toe-in is not within the specified range, inspect the suspension parts and replace if necessary.

c. INSPECT CAMBER

1. Install a camber-caster-kingpin gauge or put the wheels on a wheel alignment tester.

2. Inspect the camber.

If the measured value is not within the specified range, inspect the suspension parts for damage and wear. Replace parts as necessary because camber cannot be properly adjusted with any damaged or worn parts.
