INSPECT TOE-IN
Toe-in:
TOE-IN SPECIFICATION

Toe-in (total) A + B:0° +/- 12' (0° +/- 0.2°) C-D:0 +/- 2 mm(0 +/- 0.08 in.)

HINT:
- Measure "A + B" when "C - D" can not be measured.
- If toe-in is not within the specified range, adjust it at the rack ends.
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 an equal amount to adjust the toe-in.
  HINT:
  
  Try to adjust the toe-in to the center of the specified range.

4. Make sure that the lengths of the right and left rack ends are the same.
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 DIAGNOSTIC TROUBLE CODES CHECK/CLEAR )

  If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.
INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
1. Put the front wheel on the center of the alignment tester.
2. Set the camber-caster-kingpin gauge at the center of the axle hub or drive shaft.

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

ADJUST CAMBER

NOTE: After the camber has been adjusted, inspect the toe-in.

Remove the front wheel.
Remove the 2 nuts on the lower side of the shock absorber assy front LH.
Clean the installation surfaces of the shock absorber assy front LH 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: 210 N.m (2,141 kgf.cm, 155 ft.lbf)
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 - Measured value

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