Front Wheel Alignment: Adjustment: Adjustment
For vehicles equipped with VSC, if the wheel alignment has been adjusted, or 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 TIRES . Refer to INSPECTION - Step 1
- MEASURE VEHICLE HEIGHT
NOTE:
- 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.
- Bounce the vehicle up and down at the corners several times to stabilize the suspension.
- Measure the vehicle height.
- Measuring points (for Torsion Type Suspension):
- A: Ground clearance of front wheel center
- B: Ground clearance of lower suspension arm No. 1 bush front bolt center
- C: Ground clearance of axle beam set bolt center
- D: Ground clearance of rear wheel center
- Measuring points (for Double Wishbone Type Suspension):
- A: Ground clearance of front wheel center
- B: Ground clearance of lower suspension arm No. 1 bush front bolt center
- C: Ground clearance of No. 1 lower suspension arm bushing set bolt center

- 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.
HINT:
Try to adjust the camber to the center of the specified values.
Move the Axle toward (+) in Step B Move the Axle toward (-) in Step B Refer to table (1) (Move the axle toward the positive side) Refer to table (2) (Move the axle toward the negative side) The body and suspension may be damaged if the camber is not correctly adjusted according to the table above.
NOTE:Replace the nut with a new one when replacing the bolt.
- Repeat the steps mentioned above. In step (A), replace 1 or 2 selected bolts.
HINT:
Replace one bolt at a time when replacing 2 bolts.
- INSPECT TOE-IN
- Bounce the vehicle up and down at the corners several times 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.) *1.
