INSPECTION
1. MEASURE VEHICLE HEIGHT
Vehicle height:
Tire sizeFront*1 mm (in.)Rear*2 mm (in.)
175/65R14191 (7.52)239 (9.41)
*1: Front measuring point
Measure the distance from the ground to the head center of the
front side lower suspension arm mounting bolt.
*
2: Rear measuring point
Measure the distance from the ground to the center of the rear
axle beam mounting bolt.
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specified value.
If the vehicle height is not the specified value, try to adjust it by
pushing down on or lifting the body.
2. INSTALL CAMBER±CASTER±KINGPIN GAUGE OR
POSITION VEHICLE ON WHEEL ALIGNMENT TES-
TER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS
INCLINATION
Camber, caster and steering axis inclination:
Camber
Right±left error±0°26' ± 45' (±0.43° ± 0.75°)
45' (0.75°) or less
Caster
Right±left error1°02' ± 45' (1.03° ± 0.75°)
45' (0.75°) or less
Steering axis inclination
Right±left error9°52' ± 45' (9.87° ± 0.75°)
45' (0.75°) or less
If the caster and steering axis inclination are not within the spe-
cified values, after the camber has been correctly adjusted, re-
check the suspension parts for damaged and/or worn out parts.
4. ADJUST CAMBER
NOTICE:
After the camber has been adjusted, inspect the toe±in.
(a) Remove the front wheel.
(b) Remove the 2 nuts on the lower side of the shock absorb-
er.
If reusing the bolts and/or nuts, coat the threads of nuts with en-
gine oil.
(c) Clean the installation surfaces of the shock absorber and
the steering knuckle.
(d) Temporarily install the 2 nuts.

(e) Adjust the camber by pushing or pulling the lower side of
the shock absorber in the direction in which the camber
adjustment is required.
(f) Tighten the nuts.
Torque: 153 N´m (1,560 kgf´cm, 113 ft´lbf)
(g) Install the front wheel.
Torque: 103 N´m (1,050 kgf´cm, 76 ft´lbf)
(h) Check the camber.
HINT:

Try to adjust the camber to the center of the specified val-
ue.

Adjusting value for the set bolts is 6' ± 30' (0.1° ± 0.5°).
If the camber is not within the specified value, using the follow-
ing table, estimate how much additional camber adjustment will
be required, and select the camber adjusting bolt.
NOTICE:
Tighten the adjusting bolt with a washer and a new nut.
(i) Do the steps mentioned above again. At step (b), replace
1 or 2 selected bolts.
HINT:
When replacing the 2 bolts, replace 1 bolt for each time.

NOTICE:

The hub bearing could be damaged if it is subjected
to the vehicle weight, such as when moving the ve-
hicle with the drive shaft removed.
Therefore, if it is absolutely necessary to place the ve-
hicle weight on the hub bearing, first support it with
the SST.
