Wheel turning angle:

If the right and left inside wheel angles differ from the specified

If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.

6. Inspect camber, caster and steering axis inclination

  1. Install the cambercasterkingpin gauge or position vehicle on wheel alignment tester.
  2.  inspect the camber, caster and steering axis inclination.

    Camber, caster and steering axis inclination:

If the caster and steering axis inclination are not within the specified

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 damaged and/or worn out parts.

7. Adjust camber

Notice

: after the camber has been adjusted, inspect the toein.

  1.  remove the front wheel.

  1. Remove the 2 nuts on the lower side of the shock absorber assy front lh.
