Front Wheel Alignment: Adjustment

INSPECT TIRE (SEE FRONT WHEEL ALIGNMENT )

MEASURE VEHICLE HEIGHT

Vehicle height:

VEHICLE HEIGHT SPECIFICATIONS

	Front A - B	Rear D - C
FF	120.1 mm (4.73 in.)	40.5 mm (1.59 in.)
4WD	110.1 mm (4.33 in.)	30.5 mm (1.20 in.)

Measuring points:

Ground clearance of front wheel center
Ground clearance of lower suspension arm No.2 bush set bolt center
Ground clearance of strut rod set bolt center
Ground clearance of rear wheel center

NOTE: Before inspecting the wheel alignment, adjust the vehicle height to the specified value.

HINT:

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

ADJUST TOE-IN
1. Remove the rack boot set clips.
2. Loosen the tie rod end lock nuts.
3. Turn the right and left rack ends by equal amounts to adjust the toe-in.
  HINT:
  
  Try to adjust the toe-in to the center of the specified value.
4. Make sure that the lengths of the right and left rack ends are the same.
  Rack and length difference: 1.5 mm (0.059 in.) or less
5. Torque the tie rod end lock nuts.
  Torque: 74 N.m (755 kgf.cm, 55 ft.lbf)
6. Place the boots on the seats and install the clips.
  HINT:
  
  Make sure that the boots are not twisted.
7. Perform VSC system calibration (see PRE-CHECK ).

INSPECT WHEEL ANGLE

Turn the steering wheel fully left and right to measure the turning angle.

WHEEL TURNING ANGLE SPECIFICATIONS

	Inside wheel	Outside wheel: Reference
FF	35°28' +/- 2° (35.47° +/- 2°)	31°13' (31.22°)
4WD	35°41' +/- 2° (35.68° +/- 2°)	31°22' (31.37°)

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

INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

Put the front wheel on the center of the alignment tester.
Set the camber - caster - kingpin gauge at the center of the axle hub or drive shaft.

CAMBER, CASTER AND STEERING AXIS INCLINATION SPECIFICATIONS

	FF	4WD
Camber Right-left error	-0°40' +/- 45' (-0.67° +/- 0.75°) 45' (0.75°) or less	-0°35' +/- 45' (-0.58° +/- 0.75°) 45' (0.75°) or less
Caster Right-left error	2° 45' +/- 45' (2.75° +/- 0.75°) 45' (0.75°) or less	2°45' +/- 45' (2.75° +/- 0.75°) 45' (0.75°) or less
Steering axis inclination Right-left error	10°45' +/- 45' (10.75° +/- 0.75°) 45' (0.75°) or less	10°35' +/- 45' (10.58° +/- 0.75°) 45' (0.75°) or less

If the caster and steering axis inclination are not within the specified values after the camber has been correctly adjusted, recheck the suspension parts for damage and/or wear.

ADJUST CAMBER

NOTE: Inspect toe-in after the camber has been adjusted.

Remove the front wheel.
Remove the 2 nuts on the lower side of the shock absorber.
HINT:

When removing the nuts, keep the bolts from rotating.
Clean the installation surface of the shock absorber and the steering knuckle.
Temporarily install the 2 nuts.

Fully push or pull the front axle hub in the direction of the required adjustment.
Tighten the nuts.
Torque: 230 N.m (2,350 kgf.cm, 170 ft.lbf)

HINT:

When installing the nuts, keep the bolts from rotating and then torque the nuts.
Install the front wheel.
Torque: 103 N.m (1,050 kgf.cm, 76 ft.lbf)

NOTE: Keep the bolts from rotating and torque the nuts.
Install the front wheel.
Torque: 103 N.m (1,050 kgf.cm, 76 ft.lbf)

Check the camber.

If the measured value is not within the specified range, calculate the required adjustment amount using the formula below.

(Camber adjustment amount) = Center of the specified range medium - Measured value

Check installed bolts combination. Select appropriate bolts from the table below to adjust the camber to within the specified range.

CAMBER ADJUSTMENT SPECIFICATIONS

Move the axle toward (+) in step (e)	Refer to table (1) (Move the axle toward positive side)
Move the axle toward (-) in step (e)	Refer to table (2) (Move the axle toward negative side)
