for Preparation Click here

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:

1. Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection (Click here).
   

1. Check the tires for wear and proper inflation pressure.
   
   

   Cold Tire Inflation Pressure:

   
   

   Tire Size	Vehicle Speed	Front	Rear
   175/65R15 84S 175/60R16 82H	Driving below 160 km/h (100 mph)	230 kPa (2.3 kgf/cm2, 33 psi)	220 kPa (2.2 kgf/cm2, 32 psi)
   	Driving over 160 km/h (100 mph)	240 kPa (2.4 kgf/cm2, 35 psi)	230 kPa (2.3 kgf/cm2, 33 psi)

2. Using a dial indicator, check the runout of the tires.
   

   Tire runout:

   1.4 mm (0.0551 in.) or less (Vertical)
   

   2.0 mm (0.0787 in.) or less (Lateral)

NOTICE:

1. Before inspecting the wheel alignment, check the vehicle height.
   
2. Perform the inspection while the vehicle is empty (with the tire puncture repair kit in the vehicle and the tools removed from the vehicle).
   

HINT:

Bounce the vehicle up and down at the corners to stabilize the suspension before inspecting the vehicle height.

1. Fully turn the steering wheel left and right, and measure the wheel turning angle.

   NOTICE:

   Perform the inspection while the vehicle is empty (with the tire puncture repair kit in the vehicle and the tools removed from the vehicle).

   If the right and left inside wheel angles are not within the specified range, check the right and left rack end lengths.
   

1. Put the front wheel on the center of the alignment tester.

   NOTICE:

   1. Perform the inspection while the vehicle is empty (with the tire puncture repair kit in the vehicle and the tools removed from the vehicle).
      
   2. The tolerance for the difference between the left and right wheels is 30' (0.5°) or less for both the camber and caster.
      

5. Remove the camber-caster-steering axis inclination gauge and attachment.
   

6. Install the wheel cap.
   If the caster and steering axis inclination are not within the specified values after the camber has been correctly adjusted, recheck the suspension parts for damage and wear.
   

NOTICE:

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

1. Remove the front wheel.
   

2. Remove the 2 bolts and separate the speed sensor and flexible hose.
   

3. Remove the 2 nuts from the lower side of the shock absorber.
   

   HINT:

   Keep the bolt from rotating while loosening and removing the nuts.

4. Clean the installation surfaces of the shock absorber and steering knuckle.
   

5. Provisionally install the 2 nuts (Step A).
   

6. Fully push or pull the axle hub in the direction of the required adjustment (Step B).
   

7. Tighten the 2 nuts.
   

   Torque:

   164 N*m{ 1672 kgf*cm , 121 ft.*lbf }

   HINT:

   Keep the bolt from rotating while loosening and removing the nuts.

8. Install the flexible hose and speed sensor with the 2 bolts.
   

   Torque:

   29 N*m{ 300 kgf*cm , 22 ft.*lbf }

   Torque:

   103 N*m{ 1050 kgf*cm , 76 ft.*lbf }

10. Check the camber.
    If the measured value is not within the specifications, calculate the required adjustment amount using the formula below.
    (Camber adjustment amount) = Center of specified range - Measured value
    Check the combination of installed bolts. Select appropriate bolts from the table below to adjust the camber to within the specified range.
    

    HINT:

    Try to adjust the camber to the center of the specified range.

    Move axle toward (+) in step (B)	Refer to table (1) (Move axle toward positive side)
    Move axle toward (-) in step (B)	Refer to table (2) (Move axle toward negative side)

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

    
    
    
    

12. Table (2) (Move the axle toward the negative side).
    
    

    
    
    
    The body and suspension may be damaged if the camber is not correctly adjusted in accordance with the above table.
    

    NOTICE:

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

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

    HINT:

5. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180° using 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 the beginning again.
