Front Wheel Alignment: Adjustment

NOTE: For vehicles equipped with VSC, if wheel alignment has been adjusted, and if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:

Disconnect the negative battery terminal for more than 2 seconds.
Reconnect the negative battery terminal.
Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.

MEASURE VEHICLE HEIGHT

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

Vehicle height:

VEHICLE HEIGHT (FF) REFERENCE

Front (A - B)	Rear (D - C)
115.5 mm (4.55 in.)	-27.5 mm (-1.08 in.)

4WD

VEHICLE HEIGHT (4WD) REFERENCE

Front (A - B)	Rear (D - C)
116 mm (4.57 in.)	-45.5 mm (-1.79 in.)

Measuring points:

Ground clearance of front wheel center
Ground clearance of lower suspension arm No. 2 set bolt center
Ground clearance of rear axle carrier bushing set bolt center
Ground clearance of rear wheel center

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

HINT:

If the vehicle height is not as specified, adjust it by pushing down or lifting the body.

INSPECT TOE-IN

Inspect the toe-in.

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:
  
  Adjust the toe-in to the center of the specified value as much as possible.
4. Make sure that the lengths of the right and left rack ends are the same.
5. Tighten 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.

INSPECT WHEEL ANGLE

Turn the steering wheel fully and measure the turning angle.

Wheel turning angle:

WHEEL ANGLE REFERENCE (FF)

Inside wheel	Outside wheel
42°45' +/- 2° (42.75° +/- 2°)	36°21' (36.35°)

4WD

WHEEL ANGLE REFERENCE (4WD)

Inside wheel	Outside wheel
42°42' +/- 2° (42.70°+/-2°)	36°16' (36.27°)

HINT:

If the right and left inside wheel angles are not as specified, check the right and left rack end lengths.

INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

Install the camber-caster-kingpin gauge or position the vehicle on the wheel alignment tester.

Inspect the camber, caster and steering axis inclination.

CASTER AND CAMBER - ERROR CHART

Camber Right-left error	Caster Right-left error	Steering axis inclination Right-left error
-0°17' +/- 45' (-0.28° +/- 0.75°) 30' (0.5°) or less	3°09' +/- 45' (3.15° +/- 0.75°) 30' (0.5°) or less	10°25' +/- 45' (10.42° +/- 0.75°) 30' (0.5°) or less

4WD

CASTER AND CAMBER - ERROR CHART

Camber Right-left error	Caster Right-left error	Steering axis inclination Right-left error
-0°17' +/- 451 (-0.28° +/- 0.75°) 30' (0.5°) or less	3°00' +/- 45' (3.00° +/- 0.75°) 30' (0.5°) or less	10°12' +/- 45' (10.20° +/- 0.75°) 30' (0.5°) or less

HINT:

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 worn out parts.

ADJUST CAMBER
NOTE: After the camber has been adjusted, inspect the toe-in.
1. Remove the front wheel.
2. Remove the 2 nuts on the lower side of the shock absorber. (Procedure "B")
  NOTE: When removing the nut, hold the bolt not to rotate.
3. Clean the installation surfaces of the shock absorber and the steering knuckle.
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: 210 N*m (2140 kgf*cm, 155 ft.*lbf)
  
  NOTE: When installing the nut, stop the bolt from rotating and tighten the nut.
7. Install the front wheel.
  Torque: 103 N*m (1050 kgf*cm, 76 ft.*lbf)
8. Check the camber.

  HINT:
  - Adjust the camber to the center of the specified value as much as possible.
  - Adjusting value for the set bolts is 6' to 30' (0.1° to 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.
  NOTE: Tighten the adjusting bolt with a washer and a new nut.
9. Perform the procedure mentioned above again. At procedure "B", replace 1 or 2 selected bolts.
  HINT:
  
  Replace one bolt at a time when replacing 2 bolts.
