INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

CAMBER, CASTER AND STEERING AXIS INCLINATION SPECIFICATIONS

Camber	Right-Left Error	-0° 31' +/- 45' (-0.52° +/- 0.75°) 45' (0.75°) Or Less
Caster	Right-Left Error	2° 08' +/- 45' (2.13° +/- 0.75°) 45' (0.75°) Or Less
Steering Axis Inclination	Right-Left Error	12° 54' +/- 45' (12.90° +/- 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 damaged and/or worn out parts.

ADJUST CAMBER
NOTE: After the camber has been adjusted, inspect the toe-in.
1. Remove the front wheel and ABS speed sensor clamp.
2. Remove the 2 nuts on the lower side of the shock absorber.

3. Coat the threads of the nuts with engine oil.
4. Temporarily install the 2 nuts.
5. Adjust the camber by pushing or pulling the lower side of the shock absorber in the direction in which the camber adjustment is required.

6. Tighten the nuts.
  Torque: 220 N.m (2250 kgf.cm, 162 ft.lbf)
7. Install the ABS speed sensor clamp and front wheel.
  Torque: 103 N.m (1050 kgf.cm, 76 ft.lbf)
8. Check the camber.
  NOTE:
  - Try to adjust the camber to the center of the specified value.
  - Adjusting value for the set bolts is 6 - 30' (0.1 - 0.5°).
  If the camber is not within the specified value, using the following table, estimate how much additional camber adjustment will be required, and select the camber adjusting bolt.

9. Do the steps mentioned above again. Between steps (b) and (c), replace 1 or 2 selected bolts.
NOTE: When replacing the 2 bolts, replace 1 bolt for each time.

INSPECT TOE-IN

TOE-IN SPECIFICATIONS

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

If the toe-in is not within the specified value, 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.
  NOTE:
  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.
  
  Fig 8: Measuring Lengths Of Rack Ends

  Rack end length difference: 1.5 mm (0.059 in.) or less
5. Torque the tie rod end lock nuts.
  Torque: 74 N.m (750 kgf.cm, 54 ft.lbf)
6. Place the boots on the seats and install the clips.
CAUTION: Make sure that the boots are not twisted.
INSPECT WHEEL ANGLE

Turn the steering wheel fully, and measure the turning angle.

Fig 9: Inspecting Wheel Angle

WHEEL TURNING ANGLE SPECIFICATIONS

Inside Wheel	34° +/- 19' +/- 1° (34.32° +/- 1° )
Outside Wheel: Reference	30° 22' (30.37° )

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