(37.10° ± 2°)

31°49’ (31.82°) 32°08’ (32.13°)

37°16’ ± 2°

(37.27° ± 2°)

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

(a) Install the camber–caster–kingpin gauge or position ve-

hicle on wheel alignment tester.

(b) Inspect the camber, caster and steering axis inclination.

Camber, caster and steering axis inclination:
