FRONT WHEEL ALIGNMENT ADJUSTMENT
PROCEDURE
-
INSPECT TIRES
-
MEASURE VEHICLE HEIGHT
Note
-
Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
-
Be sure to perform the measurement on a level surface.
-
If it is necessary to go under the vehicle for measurement, make sure that the parking brake is applied and the vehicle is secured with chocks.
-
Bounce the vehicle up and down at the corners several times to stabilize the suspension.
-
Measure the vehicle height.
Measuring points A Ground clearance of center of front No. 1 lower suspension arm bushing set bolt B Ground clearance of center of rear No. 2 suspension arm bushing set bolt C Ground clearance of center of front wheel D Ground clearance of center of rear wheel Standard Vehicle Height (Unloaded Vehicle) Item Front C - A Rear D - B - 102 mm (4.02 in.) 72 mm (2.83 in.) Rough Road Package 92 mm (3.62 in.) 62 mm (2.44 in.) Note
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.
Tech Tips
If the vehicle height is not as specified, press down on the vehicle several times to stabilize the suspension. Then measure the vehicle height again.

ADJUST CAMBER
Note
Inspect toe-in after the camber has been adjusted.
-
Remove the front wheel.
-
Remove the bolt, detach the clamp and disconnect the front speed sensor.
-
Remove the bolt and disconnect the front flexible hose.
-
Remove the 2 nuts on the lower side of the front shock absorber.
Note
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.
Note
Do not apply lubricants to the steering knuckle and shock absorber contact surfaces.
Tech Tips
-
Reinstall each bolt after removing it and confirming steering knuckle movement.
-
If the steering knuckle does not move freely in the front shock absorber, clean the installation surfaces of the front shock absorber 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 nuts.

- 240 N*m { 2447 kgf*cm, 177 ft.*lbf }
Note
Prevent the bolts from rotating when tightening the nuts.
-
Connect the front flexible hose to the steering knuckle with the bolt.
- Torque:
- 29 N*m { 296 kgf*cm, 21 ft.*lbf }
-
Connect the front flexible hose and front speed sensor with the bolt.
- Torque:
- 29 N*m { 296 kgf*cm, 21 ft.*lbf }
Note
Do not twist the front speed sensor when installing it.
-
Attach the clamp of the front speed sensor.
-
Install the front wheel.
- Torque:

Check the camber.
If the measured value is not within the specification, calculate the required adjustment amount using the formula below.
Camber adjustment amount = center value of the specified range - measured value.
Check the combination of installed bolts. Select appropriate bolts from the table below to adjust the camber to the specified values.
Tech Tips
Try to adjust the camber to the center of the specified range.
Move Axle toward (+) in Step (B) Move Axle toward (-) in Step (B) Refer to table (1) (When moving the axle toward the positive side) Refer to table (2) (When moving the axle toward the negative side) Note
Replace the nut with a new one when replacing a bolt.
