ON-VEHICLE SERVICE
WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
Measure the wheel alignment with the vehicle parked on a
level surface.
The front suspension, steering system, and wheels should be
serviced to normal condition prior to measurement of wheel
alignment.
TOE-IN
Standard value:
At the centre of tyre tread 0±2mm
Toe angle (per wheel) 0_00’±05’
1. Adjust the toe-in by undoing the clip and lock nut, and
turning the left and right tie rod turnbuckles by the same
amount (in opposite directions).
NOTE
The toe will move out as the left turnbuckle is turned
toward the front of the vehicle and the right turnbuckle
is turned toward the rear of the vehicle.
2. Install the clip and tighten the lock nut to the specified torque.

3. Confirm that the toe-in is at the standard value.
4. Use a turning radius gauge to check that the steering
angle is at the standard value.
Standard value:
Inner wheels31_45’±1_30’

TOE-OUT ANGLE ON TURNS
To check the steering linkage, especially after the vehicle
has been involved in an accident or if an accident is presumed,
it is advisable to check the toe-out angle on turns in addition
to the wheel alignment.
Conduct this test on the left turn as well as on the right turn.
Standard value:

1. Use the special tools to compress the coil spring.
Caution
(1) Do not tighten the special tool bolt too tight. The
special tool will be broken if the allowable
tightening torque of 74 N·m is exceed.
(2) Install the special tools evenly, and so that the
maximum length will be attained within the
installation range.
(3) Do not use an impact wrench as it will cause the
bolt of the special tool to be seized.
2. Using the special tools, loosen the self-locking nut.
Caution
To prevent the piston rod lock nut inside the strut
from loosening, do not use an impact wrench when
the self-locking nut is loosened.

AB"STRUT ASSEMBLY REMOVAL
To discard the strut assembly, place the assembly horizontally
with its piston rod extended. Then drill a hole approx. 3 mm
in diameter at the location shown in the illustration and
discharge the gas.
Caution
The gas itself is harmless but it may issue out of the
hole together with chips generated by the drill. Therefore,
be sure to wear goggles.
REASSEMBLY SERVICE POINT
"AASELF-LOCKING NUT INSTALLATION
1. Ensure that the bearing is seated correctly.
2. Install the special tool to the strut assembly same as
its removal.
3. While the coil spring is being compressed by the special
tools, provisionally tighten the self-locking nut.
Caution
Do not use an impact wrench as it will cause the
bolt of the special tool to be seized.
4. Align the hole in the strut assembly lower spring seat
with the hole in the upper spring seat.
NOTE
Using a pipe as shown facilitates the alignment.
5. Correctly align both ends of the coil spring with the grooves
in the spring seat, and then loosen the special tools.
6. Using the special tools, tighten the self-locking nut to the
specified torque.
Specified torque: 60±10 N·m
Caution
To prevent the piston rod lock nut inside the strut
from loosening, do not use an impact wrench when
the self-locking nut is tightened.
7. After tightening self-locking nut, fill the multi purpose
greese to the bearing part of strut insulator.

REMOVAL AND INSTALLATION
Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
2. *: To prevent bushings from breakage, the parts indicated by * should be temporarily tightened,
and then fully tightened with the vehicle on the ground in the unladen condition.

INSPECTION
LOWER ARM BALL JOINT ROTATION STARTING
TORQUE CHECK
1. After shaking the ball joint stud several times, use the
special tool to measure the rotation starting torque of
the lower arm ball joint.
Standard value: 0.5 - 3.4 N·m
2. When the measured value exceeds the standard value,
replace the lower arm assembly.
3. When the measured value is lower than the standard
value, check that the lower arm ball joint turns smoothly
without excessive play. If there is no excessive play, the
ball joint can be reused.
PILLOW BALL BUSHING ROTATION STARTING
TORQUE CHECK
1. Insert the bolt to the lower arm pillow ball bushing, in
the opposite direction, insert the washer then install the
nut. After rotating the inner sleeve (contained washer)
several times, measure the rotation starting torque of
the lower arm pillow ball bushing using special tool.
Standard value: 0.5 - 3.0 N·m
2. When the measured value exceeds the standard value,
replace the pillow ball bushing.
3. When the measured value is lower than the standard
value, check that the lower arm pillow ball bushing turns
smoothly without excessive play. If there is no excessive
play, the pillow ball bushing can be reused.
LOWER ARM BALL JOINT DUST COVER CHECK
1. Check the dust cover for cracks or damage by pushing
it with finger.
2. If the dust cover is cracked or damaged, replace the
lower arm assembly.
NOTE
If the dust cover is cracked or damaged, it is possible
that there may also be damage to the ball joint.
When it is damaged during service work, replace the
dust cover.

2. Apply multipurpose grease to the lip and inside of the
dust cover.
3. Using the special tool, press the dust cover until it contacts
the lower arm assembly.
4. Press the dust cover with your finger to check that there
are no cracks or damage in the dust cover.
LOWER ARM PILLOW BALL BUSHING
REPLACEMENT
Replace the bushing as follows:
1. Use the special tools to drive out the bushing.

REMOVAL AND INSTALLATION
Caution
1. Before removing the steering wheel and air bag module assembly, refer to GROUP 52B - Service
Precautions and Air Bag Module and Clock Spring. Also, put the front wheels in straight-ahead
position. Failure to do so may damage the SRS clock spring and render the SRS air bag
inoperative, which results serious driver injury.
2. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
3. To prevent bushings from breakage, the parts indicated by * should be temporarily tightened,
and then fully tightened with the vehicle on the ground in the unladen condition.
