Camber: 

Caster: 

Steering axis inclination: 

If the caster and steering axis inclination are not within the specification, after the camber has correctly adjusted, recheck the suspension parts for damaged and/or worn out parts.

HINT:

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.

6. Tighten the 2 nuts.

   Torque: 143 N.m (1,460 kgf.cm, 105 ft.lbf) 

7. Install the front wheel.

   Torque: 103 N.m (1,050 kgf.cm, 76 ft.lbf) 

8. Check the camber.

   HINT:

   • Try to adjust the camber to the center of the specified value.
   • Adjusting value for the set bolts is 6' - 30' (0.1° - 0.5°).

   If the camber is not within the specification, estimate how much additional camber adjustment will be required and select the camber adjusting bolt using Fig 6.
