*1: Front measuring point
Measure from the ground to the center of the lower suspension
arm mounting bolt.
*
2: Rear measuring point
Measure from the ground to the center of the No.2 lower sus-
pension arm mounting bolt.
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specification.
If the vehicle height is not within the specification, try to adjust
it by pushing down on or lifting the body.
2. INSTALL CAMBER±CASTER±KINGPIN GAUGE

Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS

5. ADJUST CAMBER
HINT:

After adjusting the camber, inspect the caster and toe±in.

Try adjusting the camber to the center value of the specifi-
cation.
(a) Loosen the camber adjusting cam nut of the lower sus-
pension arm.
(b) Turn the camber adjusting cam of the lower suspension
arm and adjust camber.
HINT:
Camber changes about 5' (0.08°) with each graduation of the
adjusting cam.
(c) Torque the camber adjusting cam nut of lower suspension
arm.
Torque: 172 N´m (1,755 kgf´cm, 127 ft´lbf)
6. ADJUST TOE±IN
(a) Remove the boot clips.
(b) Loosen the tie rod end lock nuts.
(c) Turn the left and right rack ends an equal amount to adjust
the toe±in.
HINT:

Try to adjust the toe±in to the center value.

Make sure that the lengths of the left and right rack ends
are same.
Rack end length difference: 1.5 mm (0.059 in.) or less
(d) Torque the tie rod end lock nuts.
Torque: 56 N´m (570 kgf´cm, 41 ft´lbf)
(e) Place the boot on the seat and clamp it.
HINT:
Make sure that the boots are not twisted.
