Front Wheel Alignment: Adjustment

NOTE: For vehicles equipped with VSC, if the 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 cable from the negative battery terminal for more than 2 seconds.
Reconnect the cable to the negative battery terminal.
Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.

INSPECT TIRE
1. Inspect the tire (See INSPECTION ).

Measuring points:

Ground clearance of front wheel center
Ground clearance of front suspension arm sub-assembly 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:

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

INSPECT TOE-IN

Inspect the toe-in.

Toe-in

TOE-IN SPECIFICATION

Toe-in: (total)	-
A + B: C - D:	0° +- 6' (0° +- 0.1°) 0 +- 1 mm (0 +- 0.04 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.
  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. with VSC:
  Perform VSC system calibration (See CALIBRATION ).

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

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.

Camber, caster and steering axis inclination:

Remove the 2 nuts on the lower side of the shock absorber.
NOTE: Keep the bolts inserted.
Clean the installation surfaces of the shock absorber and the steering knuckle.
Fully push or pull the front axle hub in the direction of the required adjustment.
Tighten the nuts.
