Front Wheel Alignment: Adjustment

Vehicle Height: 

Measuring points: 

A: Ground clearance of front wheel center 

B: Ground clearance of lower suspension arm No.2 bush set bolt center 

C: Ground clearance of strut rod set bolt center 

D: Ground clearance of rear wheel center 

HINT:

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

Toe-in: 

If the toe-in is not within the specified range, adjust it at the rack ends.

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 ).

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

   Wheel turning angle: 

   WHEEL TURNING ANGLE
   
   

   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.

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 values after the camber has been correctly adjusted, recheck the suspension parts for damage and/or wear

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

   HINT:

   When removing the nuts, keep the bolts from rotating.

3. Clean the installation surface of the shock absorber and the steering knuckle.
4. Temporarily install the 2 nuts.
5. Fully push or pull the front axle hub in the direction of the required adjustment.
6. Tighten the nuts.

   Torque: 230 NVm (2,350 kgfVcm, 170 ftVlbf) 

   HINT:

   When installing the nuts, keep the bolts from rotating and then torque the nuts.

7. 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.
8. Install the front wheel.

   Torque: 103 NVm (1,050 kgfVcm, 76 ftVlbf) 

9. 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
