7. Install the front wheel.

   Refer to PROCEDURE - Step 1

8. Bounce the vehicle up and down at the corners to stabilize the suspension.
9. Check the camber.

   Camber (Unloaded Vehicle)

   Camber Inclination	Right-left Difference
   -0°16' +/- 0°45' (-0.27° +/- 0.75°)	0°45' (0.75°) or less

   1. 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.

      NOTE:

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

10. 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.

1. Bounce the vehicle up and down at the corners to stabilize the suspension.
2. Release the parking brake and move the shift lever to N.
3. Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)
4. Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

   *b	Dimension B
   	Front of the Vehicle

5. 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.

6. Measure the distance between the tread center marks on the front of the wheels (dimension A).

   Toe-in (Unloaded Vehicle)

   Specified Condition
   C + D: 0°11' +/- 0°09' (0.18° +/- 0.15°)
   B - A: 2.4 +/- 2.0 mm (0.0945 +/- 0.0787 in.)

   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.

1. Separate the steering rack boot clips from the steering rack boot.
2. Loosen the tie rod assembly lock nuts.

3. 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.
4. Measure the toe-in.
