Measuring points:

Ground clearance of front wheel center
Ground clearance of front suspension arm subassembly lower No. 2 set bolt head 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:

INSPECT TOE-IN

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 "C - D" only when "A + B" cannot 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 toe-in.
  HINT:
  
  Try to adjust 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.

INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

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

Inspect the camber, caster and steering axis inclination.

Check the suspension parts for damaged and/or worn out parts if the caster and steering axis inclination are not within the specified range after the camber has been correctly adjusted.

ADJUST CAMBER

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

Remove the 2 nuts on the lower side of the shock absorber.
NOTE: Keep the bolts inserted.

Tighten the nuts.
Torque: 210 N*m (2,140 kgf*cm, 155 in.*lbf)

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

Check the camber.

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

OK: (Camber adjustment amount) = 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.
