Toe–in:
If the toe–in is not within the specified value, adjust it at the rack ends.
4. Adjust toe–in

are the same.
Rack end length difference: 1.5 Mm (0.059 In.) Or less
- torque the tie rod end lock nuts.
Torque: 74 n·m (755 kgf·cm, 55 ft·lbf)

Wheel turning angle:
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
- Install the camber–caster–kingpin gauge or position vehicle on wheel alignment tester.
- 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 values, after the camber has been correctly adjusted, recheck the suspension parts for damaged and/or worn out parts.
7. Adjust camber
