PROCEDURE
1.INSPECT TIRES
Inspect the tires for wear and proper inflation pressure.
Check the runout of the tires.
2.MEASURE VEHICLE HEIGHT
- NOTICE:
- ·
Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
·Be sure to perform measurement on a level surface.
·If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.
·Inspect while the vehicle is unloaded.
·The standard value shown here is a value that is used for performing a wheel alignment and does not indicate the height of an actual vehicle.
Bounce the vehicle up and down at the corners to stabilize the suspension.
Measure the vehicle height.
A: Ground clearance of front wheel center
B: Ground clearance of center of bolt head of front lower No. 2 suspension arm bushing (rear bolt of front lower No. 1 suspension arm sub-assembly).
C: Ground clearance of rear wheel center
D: Ground clearance of center of tip of threaded portion of rear lower No. 2 suspension arm assembly and rear suspension member sub-assembly.
- Vehicle Height (Unloaded Vehicle):
Front A - B Rear C - D 133 mm (5.2362 in.) 60 mm (2.3622 in.)
3.INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
- NOTICE:
-
Inspect while the vehicle is unloaded.
| *a | Turning Radius Gauge |
| *b | Camber-caster-kingpin Gauge |
Install a camber-caster-kingpin gauge and place the front wheels on the center of a turning radius gauge.
Inspect the camber, caster and steering axis inclination.
- Camber (Unloaded Vehicle):
Camber Inclination Right-left Difference -0°20' +/- 0°45' (-0.33° +/- 0.75°) 0°45' (0.75°) or less
- Caster (Unloaded Vehicle):
Caster Inclination Right-left Difference 5°00' +/- 0°45' (5.00° +/- 0.75°) 0°45' (0.75°) or less
- Steering Axis Inclination (Unloaded Vehicle):
Steering Axis Inclination Reference 12°30' (12.50°)
4.ADJUST CAMBER
- NOTICE:
-
Inspect toe-in after the camber has been adjusted.
Remove the front wheel.

Remove the 2 nuts on the lower side of the front shock absorber assembly.
- NOTICE:
-
Keep the bolts inserted.
Remove the top and bottom bolts one at a time and confirm that the steering knuckle can move freely in the front shock absorber assembly.
- HINT:
- ·
Reinstall each bolt after removing it and confirming steering knuckle movement.
·If the steering knuckle does not move freely in the front shock absorber assembly, clean the contact surfaces of the front shock absorber assembly and the steering knuckle.
Temporarily install the 2 nuts. (Step A)
Fully push or pull the front axle hub in the direction of the required adjustment. (Step B)
Tighten the 2 nuts.
- Torque:
- 290 N*m (2957 kgf*cm, 214 ft.*lbf)
- NOTICE:
-
Keep the bolts from rotating when tightening the nuts.
Install the front wheel.

Bounce the vehicle up and down at the corners to stabilize the suspension.
Check the camber.
- Camber (Unloaded Vehicle):
Camber Inclination Right-left Difference -0°20' +/- 0°45' (-0.33° +/- 0.75°) 0°45' (0.75°) or less
If the measured value is not within the specification, calculate the required adjustment amount using the formula below.
Camber adjustment amount = center of the specified range - measured value
Check the combination of the installed bolts. Select appropriate bolts from the tables below to adjust the camber to the specified values.
- HINT:
-
Try to adjust the camber to the center of the specified values.
| To move the axle hub toward (+) in step B | To move the axle hub toward (-) in step B |
|---|---|
| Refer to table (1) (To move the axle hub toward the positive side) | Refer to table (2) (To move the axle hub toward the negative side) |
The vehicle body and suspension may be damaged if the camber cannot be correctly adjusted according to the table above.
- NOTICE:
-
Replace the nut with a new one when replacing the bolt.
Table (1) (To move the axle hub toward the positive side)
| *A | Table (1) (To move the axle hub toward the positive side) | *B | Selected Bolt Combination |
| *a | Installed Bolt | *b | Adjusting Value |
| *c | Standard Bolt | *d | 90105-17013 |
| *e | 90105-17014 | *f | 90105-17015 |
Table (2) (To move the axle hub toward the negative side)
| *A | Table (2) (To move the axle hub toward the negative side) | *B | Selected Bolt Combination |
| *a | Installed Bolt | *b | Adjusting Value |
| *c | Standard Bolt | *d | 90105-17013 |
| *e | 90105-17014 | *f | 90105-17015 |
If the camber was out of adjustment in the previous step, perform the adjust camber steps mentioned above. In step A, replace the existing bolts with the selected bolts.
- HINT:
-
Replace one bolt at a time when replacing both bolts.
5.INSPECT TOE-IN
- NOTICE:
-
Inspect while the vehicle is unloaded.
Bounce the vehicle up and down at the corners to stabilize the suspension.
Release the parking brake and move the shift lever to N.
Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)
| *a | Tread Center Mark |
| *b | Dimension B |
|
Front of the Vehicle |
Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).
Slowly push the vehicle straight ahead to cause the front wheels to rotate 180°. Use the front tire valve as a reference point.
- HINT:
-
Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from step C again.
| *a | Dimension A |
|
|
Front of the Vehicle |
Measure the distance between the tread center marks on the front of the wheels (dimension A).

- HINT:
-
Measure "B - A" only when "C + D" cannot be measured.
If the toe-in is not within the specified range, adjust it at the steering rack ends.
6.ADJUST TOE-IN
Separate the steering rack boot clips from the steering rack boot.
Loosen the tie rod assembly lock nuts.
Turn the right and left steering rack ends by an equal amount to adjust the toe-in.
- HINT:
- ·
If the toe-in measurement is greater than the specified range (too much toe-out), extend the shorter rack end so that the difference in length is within the specified range.
·If the toe-in measurement is less than the specified range (too much toe-in), shorten the longer rack end so that the difference in length is within the specified range.
|
|
Front of the Vehicle |
Measure the toe-in.
- Toe-in (Unloaded Vehicle):
Specified Condition 225/60R18 C + D: 0°13' +/- 0°10' (0.22° +/- 0.17°) B - A: 2.5 +/- 2.0 mm (0.0984 +/- 0.0787 in.) 225/55R19 C + D: 0°13' +/- 0°10' (0.21° +/- 0.17°) B - A: 2.5 +/- 2.0 mm (0.0984 +/- 0.0787 in.)
- HINT:
-
Perform adjustments so that the value is as close as possible to the median of the specified range.
Tighten the tie rod assembly lock nuts.
Place the steering rack boots on the seats and install the steering rack boot clips.
7.INSPECT WHEEL ANGLE
| *a | Inside |
| *b | Outside |
|
|
Front of the Vehicle |
Put tread center marks on the rearmost points of a turning radius gauge.
Turn the steering wheel fully to the left and right and measure the turning angle.
- NOTICE:
-
Inspect while the vehicle is unloaded.
- Wheel Turning Angle (Unloaded Vehicle):
Tire Size Inside Wheel Outside Wheel 225/60R18 37°15' +/- 2°00' (37.25° +/- 2.00°) 32°10' (32.17°) 225/55R19 35°15' +/- 2°00' (35.25° +/- 2.00°) 30°50' (30.83°)
