Front Wheel Alignment

SUSPENSION: FRONT WHEEL ALIGNMENT (for AWD): ADJUSTMENT

NOTICE:
* When the wheel alignment is performed, or a suspension related part is removed and installed/replaced, make sure to the cable from the negative (-) battery terminal for 2 seconds or more after finishing, and then reconnect the cable and perform initialization.
* If the vehicle is equipped with a VSC system, when the wheel alignment is performed, or a suspension related part is removed and installed/replaced, always perform the following initialization so that the system can function normally: (1) Disconnect the cable from the negative (-) battery terminal for 2 seconds or more and then reconnect it; then (2) perform the yaw rate sensor zero point calibration and test mode inspection.
* If the vehicle has an object recognition camera, after the wheel alignment is performed, always adjust the object recognition camera.

1. ADJUST FRONT SUSPENSION MEMBER

NOTICE:
* Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
* The standard value shown here is a value that is used for adjusting the wheel alignment and does not indicate the height of an actual vehicle.

If the vehicle height is not as specified, adjust the height by pressing down on the vehicle several times to stabilize the suspension.

4. MEASURE VEHICLE HEIGHT (w/ Air Suspension)

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

Standard vehicle height (unloaded):

(d) Refer to the adjustment table to make adjusting easier.

(e) Refer to the following example on how to use the adjustment table.

Standard value (reference):

Measured value (reference):

(1) Calculate the adjustment value by using the formula below.

Adjustment value (reference):

Formula:

Adjustment Value = Measured Value - Standard Value

(2) Mark the adjustment value point on the adjustment table. Then obtain the adjusting cam turning distance from the adjustment table so that the adjustment value point becomes zero.

Amount to turn adjusting cams (by gradation):

(f) Adjustment Table

(g) Tighten the nut of the adjusting cam (front side) and the bolt of the adjusting cam (rear side).

(h) Inspect the toe-in.

(i) Inspect side slip.

7. ADJUST CAMBER

(a) If the right and left camber values are not within the specified value even though the camber and caster have been adjusted with the toe adjusting cam and camber adjusting cam, replace the inner No. 1 and No. 2 arm attachment plates and perform the camber adjustment.

Standard:

HINT
For +2 mm parts, the upper arm installation hole is further toward the outside of the vehicle compared to standard parts.

8. INSPECT TOE-IN

(a) Bounce the vehicle up and down at the corners to stabilize the suspension and inspect toe-in.

Toe-in:

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

9. ADJUST TOE-IN

(a) Measure the thread lengths of the right and left rack ends.

Standard:

Difference in thread length of 1.5 mm (0.0591 in.) or less

(b) Remove the rack boot set clips.

(c) Loosen the tie rod end lock nuts.

(d) Adjust the rack ends if the difference in thread length between the right and left rack ends is not within the specified range.

(1) Extend the shorter rack end if the measured toe-in deviates toward the outer-side.

(2) Shorten the longer rack end if the measured toe-in deviates toward the inner-side.

(e) 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.

(f) Make sure that the lengths of the right and left rack ends are the same.

(g) Tighten the tie rod end lock nuts.

Torque : 56 Nm (571 kgf-cm, 41 ft-lbf)

NOTICE:
Partially tighten the lock nut while holding the hexagonal part of the steering rack end so that the lock nut and the steering rack end do not turn together. Hold the width across flat of the tie rod end and tighten the lock nut.
