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 any damage and/or worn-out parts.
ADJUST CAMBER
NOTE: After the camber has been adjusted, inspect the TOE-IN.
1. Remove the front wheel.
2. Remove the 2 nuts on the lower side of the shock absorber.

4. Temporarily install the 2 nuts.
5. Adjust the camber by pushing or pulling the lower side of the shock absorber in the direction in which the camber adjustment is required.
6. Tighten the nuts.
  Torque: 132 N.m (1,350 kgf.cm, 97 ft.lbf)
7. Install the front wheel.
  Torque: 103 N.m (1,050 kgf.cm, 76 ft.lbf)
8. Check the camber.
  HINT:
  - Adjust the camber to the center of the specified value.
  - Adjusting value for the set bolts is 6' to 30' (0.1° to 0.5°).
  If the camber is not within the specified value, using the following table, estimate how much additional camber adjustment will be required, and select the camber adjusting bolt.
  
  NOTE: Tighten the adjusting bolt with a washer and a new nut.
