1. HEADLIGHT AIMING
NOTE:
Aiming of this headlight can be adjusted only in the
vertical direction. It cannot be adjusted in the hori-
zontal direction.
CAUTION:
Turn off the light before adjusting the headlight
beam level. If it is necessary to inspect the
beam level, do not turn on the lamp for more
than two minutes.
NOTE:
Before checking the headlight beam level, be sure
of the following:
•Check the area around the headlight for any
scratches, damage or other type of deformation.
•Make sure that the vehicle is parked on a level
surface.
•Make sure that the inflation pressure of tires are
correct.
•Check that the vehicle fuel tank is full.
1) Bounce the vehicle several times to normalize
the suspension.
2) Make certain that someone is seated in the driv-
er's seat.

CAUTION:
•All airbag system wiring harness and con-
nectors are colored yellow. Do not use electri-
cal test equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the center brake
pipe.
•When installing the brake pipe, do not bend.

C: DISASSEMBLY
1) Using a coil spring compressor, compress the
coil spring.
2) Using the ST, remove the self–locking nut.
ST 20399AG000 STRUT MOUNT SOCKET
3) Remove the strut mount, spacer and upper
spring seat from strut.
4) Gradually decrease the compression force of
compressor, and remove the coil spring.
5) Remove the dust cover and helper spring.
D: ASSEMBLY
1) Before installing the coil spring, strut mount, etc.
on strut, check for the presence of air in the damp-
ening force generating mechanism of the strut
since air prevents proper dampening force produc-
tion.
2) Checking for presence of air
(1) Place the strut vertically with the piston rod
facing up.
(2) Move the piston rod to the center of its entire
stroke.
(3) While holding the piston rod end with fin-
gers, move the rod up and down.
(4) If the piston rod moves more than 10 mm
(0.39 in) in the former step, purge air from the
strut.
3) Air purging procedure
(1) Place the strut vertically with the piston rod
facing up.
(2) Fully extend the piston rod.
(3) With the piston rod fully extended, place the
piston rod side down. The strut must stand ver-
tically.
(4) Fully retract the piston rod.
(5) Repeat 3 or 4 times from the step (1).
NOTE:
After purging air from the strut, be sure to place the
strut with the piston rod facing up. If the strut is laid
down for any reason, check for the entry of air in ac-
cordance with “Checking for presence of air”
4) Using a coil spring compressor, compress the
coil spring.
NOTE:
Make sure that the vertical install direction of the
coil spring is as shown in the figure.
5) Set the coil spring correctly so that its end face
seats well in the spring seat as shown in the figure.
6) Install the helper and dust cover to the piston
rod.

NOTE:
Position the upper spring seat as shown in the fig-
ure.
8) Install spacer and the strut mount to piston rod,
and tighten a new self-locking nut temporarily.

from turning, tighten the new self-locking nut with
ST.

10) Loosen the coil spring carefully.
E: INSPECTION
Check the removed part for wear, damage and
cracks, and then repair or replace it if defective.
1. DAMPER STRUT
1) Check for oil leaks.
2) Move the piston rod up and down to check that it
operates smoothly without any hitch.
3) Piston rod play
•Measure the play as follows:
Fix the outer shell in place and fully extend the rod.
Set a dial gauge at the end of rod L [10 mm (0. 39
in)], and then read the dial gauge indication P1while applying a force of W [20 N (2 kgf, 4 lb)] to the
threaded portion. Apply a force of 20 N (2 kgf, 4 lb)
from the opposite direction of “W”, and then read
the dial gauge indication P2.
Play limit (P1 + P2):
0.8 mm (0.031 in)
If the play exceeds limit, replace the strut.
2. STRUT MOUNT
Check the rubber part for deformation, cracks or
deterioration, and then replace it with a new one if
defective.
3. DUST COVER
If any cracks or damage are found, replace it with a
new one.
4. COIL SPRING
If a permanent strain is found, replaced it with a
new part.
5. HELPER
Replace it with a new one if cracked or damaged.

A: INSPECTION
*1 If the tires or wheels are wider than standard, the load to the power steering system is increased. Accordingly, in a condition,
for example before fluid warms-up, relief valve may work before reaching maximum turning angle. In this case, steering effort
may be heavy. When the measured hydraulic pressure is normal, there is no abnormal thing. *2 In cold weather, flow resistance will increase due to the cold hydraulic fluid, and steering effort will be heavier. After warming-up en-
gine, turn the steering wheel from stop to stop several times to warm-up fluid. If steering effort reduces normally, function is normal. *3 I n c o l d w e a t h e r o r w i t h i n s u f f i c i e n t w a r m – u p o f t h e e n g i n e , s t e e r i n g e f f o r t m a y b e h e a v y d u e t o e x c e s s i v e d r o p o f i d l e r p m w h en
turning the steering wheel. In this case, start the vehicle with increasing engine speed than usual. If steering effort reduces nor-
mally, function is normal.

POWER ASSISTED SYSTEM (POWER STEERING)
1. NOISE & VIBRATION
CAUTION:
Do not keep the relief valve operated over five seconds at any time or inner parts of the oil pump may
be damaged due to rapid increase of fluid temperature.
NOTE:
•A screeching noise may be heard immediately after the engine start in extremely cold conditions. In this
case, if the noise goes off during warm-up there is no abnormal function in the system. This is due to the fluid
characteristics in extremely cold condition.
•The oil pump normally makes a small whining noise due to its mechanism. Even if a noise is heard when
steering wheel is turned at stand still, there is no abnormal function in the system provided that the noise
eliminates when the vehicle is driving.
•When turning the steering wheel with the brake applied when the vehicle is parked, a screeching noise
may be generated by the brake disc and pads. This is not a fault in the steering system.
•There may be a small vibration around the steering devices when turning the steering wheel at standstill,
even though the component parts are operating properly.
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise be-
cause of combined conditions, i.e., road surface and tire surface, engine speed and turning speed of steering
wheel, fluid temperature and braking condition.
These conditions do not indicate a problem in the system.
Confirm vibration for an AT model, by applying the parking brake on a concrete surface, shifting into the “D”
range, and turning the steering wheel repeatedly from slow to rapid, step by step.
