Adjustment (to 12/2010)

SUSPENSION: FRONT WHEEL ALIGNMENT: ADJUSTMENT

NOTICE:
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:

(a) Disconnect the cable from the negative battery terminal for more than 2 seconds.
(b) Reconnect the cable to the negative battery terminal.
(c) Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.

1. INSPECT TIRE

(a) Inspect the tire Inspection (to 12/2010).

2. MEASURE VEHICLE HEIGHT

(a) Measure the vehicle height.

Vehicle height (Unloaded Vehicle):

Measurement points:

A
Ground clearance of front wheel center

B
Ground clearance of front suspension arm sub-assembly lower No. 2 set bolt head center

C
Ground clearance of strut rod set bolt center

D
Ground clearance of rear wheel center

NOTICE:
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.

3. INSPECT TOE-IN

(a) Inspect the toe-in.

Toe-in (Unloaded Vehicle):

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.

4. ADJUST TOE-IN

(a) Remove the rack boot set clips.

(b) Loosen the tie rod end lock nuts.

(c) 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.

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

(e) Torque the tie rod end lock nuts.

Torque : 74 Nm (755 kgf-cm, 55 ft-lbf)

(f) Place the boots on the seats and install the clips.

HINT
Make sure that the boots are not twisted.

(g) with VSC:

Perform VSC system calibration Calibration (to 12/2010).

5. INSPECT WHEEL ANGLE

(a) Turn the steering wheel fully left and right and measure the turning angle.

Wheel turning angle (Unloaded Vehicle):

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

6. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

(a) Put the front wheel on the center of the alignment tester.

(b) Install the camber-caster-kingpin gauge at the center of the axle hub or drive shaft.

(c) Inspect the camber, caster and steering axis inclination.

Camber, caster and steering axis inclination (Unloaded Vehicle):

Check the suspension parts for damaged and/or worn out parts if the caster and steering axis inclination are not within the specified range after the camber has been correctly adjusted.

7. ADJUST CAMBER

NOTICE:
Inspect toe-in after the camber has been adjusted.

(a) Remove the front wheel.

(b) Remove the 2 nuts on the lower side of the shock absorber.

NOTICE:
Keep the bolts inserted.

(c) Clean the installation surfaces of the shock absorber and the steering knuckle.

(d) Temporarily install the 2 nuts.

(e) Fully push or pull the front axle hub in the direction of the required adjustment.

(f) Tighten the nuts.

Torque : 290 Nm (2,957 kgf-cm, 214 ft-lbf)

NOTICE:
Keep the bolts from rotating and torque the nuts when installing the nuts.

(g) Install the front wheel.

Torque : 103 Nm (1,050 kgf-cm, 76 ft-lbf)

(h) Check the camber.

If the measured value is not within the specification, calculate the required adjustment amount using the formula below.

HINT
(Camber adjustment amount) = Specified range medium - measured value

Check installed bolts combination. Select appropriate bolts from the table below to adjust the camber to within the specified range.

(1) Table (1) (Move the axle toward positive side)

The body and suspension may be damaged if the camber is not correctly adjusted according to the above table.

NOTICE:
Replace the nut with a new one when replacing the bolt.

(j) Repeat the steps mentioned above. At step (b), replace 1 or 2 selected bolts.

HINT
Replace one bolt at a time when replacing 2 bolts.

8. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

9. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

NOTICE:
Disconnect the cable from the negative battery terminal for more than 2 seconds.

10. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.

11. PERFORM YAW RATE SENSOR ZERO POINT CALIBRATION

HINT
Perform yaw rate sensor zero point calibration Calibration (to 12/2010).

12. CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION

HINT
Check steering angle sensor zero point calibration Vehicle Stability Control System (to 12/2010).
