Removal of the front shock absorber assy

Precaution: Before the procedure below, the
careless pull may lead the disconnection of
the harness if the ABS vehicle speed sensor is
not removed first. Therefore, before the
following procedure, remove the ABS vehicle
speed sensor (the axle side) first and fix it in
a proper position in order to keep the sensor
untouched during the vehicle maintaining.

----Remove the wheel. Then loosen the joint

bolt of the propeller shaft and the brake
disc.

----Use the special socket wrench to remove the

joint bolt of the shock absorber strut and
the steering knuckle arm. (shown as the
illustration)

----Use special purpose tools to remove and

install the shock absorber coil spring.
(shown as the illustration) During the
removal, push down the vibration isolator
assy of the coil spring by puller first,
compress the coil spring, and then loosen
the piston rod nut to release the tension of
the coil spring.

Caution: The removal of the piston rod nut is
extremely dangerous, because the shock
absorber and the spring will burst out under
tremendous pressure which could cause
injury or even death. Please make sure the
shock absorber is fixed properly before the
removal of the piston rod nut.

Installation of the front shock absorber
(refer to the installation illustration of the
front strut assy)

----Assemble the front cover dust 2 with the

front bumper block 3, and then cover them
onto the piston rod of the front shock
absorber 1.

----Set on the front coil spring 8 and compress it

less than 200~220mm.

----Amount the washer 7, the front spring top

tray 6, the bearing and vibration isolator
assy 5 in sequence, and tighten the slotted
nut 4 to the specified torque (40N•m), then
loosen the compressing tools on the coil
spring.

Precaution: Please note that the two ends of the

front coil spring should reach the corresponding

locating positions of the spring trays.

Inspection of the shock absorber: The
methods for checking the shock absorber are
as following:

----Method of hand pressing the vehicle body.

Shake the vehicle body for times on the
side of the shock absorber which required
to be checked and feel whether it is
available. After the pressing, the vehicle
will shake 2-3 times and then stop, which
means the shock absorber works well.

----Method of observation. The shock absorber

should not leak oil at outside appearance.
A little oil stain is normal. If there is
serious leakage, the shock absorber should
be replaced.

----Method of touch. After long time running,

touch the exterior of the shock absorber to
check whether it is hot. If not hot, the
shock absorber is in trouble.

----Method of pulling and pressing. Place the

piston rod of the shock absorber upwards,
then pull and press it by hand for times and
check:

a whether there is a force during pulling and

pressing which means the force is large
while pulling up and small while pressing
down.

b whether there is idle stoke during pulling and

M-17

pressing which means there is a force in
lower part and not abruptly in upper part
while pulling; there is a force in lower part
and not in upper part while pressing.

c whether the shock absorber is locked and

unable to pull.

d whether the piston rod of shock absorber is

severely loose.

Note: The above phenomenons indicate the

failures of the shock absorber.

Deal with the front shock absorber

Caution:

Whenever drilling on the shock absorber,
please wear the goggles. The air pressure
in the shock absorber could probably blow
the metal flakes into eyes or face.

----Clamp the shock absorber on flat ground or

point the piston downwards to the clamped
absorber.

----Drill a hole of 2-3mm diameter at a distance

of 20-30mm to the bottom of the tube in
order to emit the air of the tube.

----Turn the shock absorber to make the hole

downwards.

----Move the piston rod up and down for times

to concentrate the oil, then cut the tube at
the end.

----Process the waste oil according to the waste

disposal method.

Note:

The shock absorber air is nitrogen.

The shock absorber oil is mineral oil.

REMOVAL AND INSTALLATION OF THE FRONT WHEEL BEARING

Removal:

----Remove the front brake disc and the dust

plate, and then extrude the hub.

----Remove the spring retainer of both sides and

extrude the wheel bearing. (shown as the
illustration)

----Pull out the bearing inner race. Use the puller

with hoop to pull the wheel bearing inner
race out of the wheel hub. (shown as the
illustration)

Inspection:

----After all the components are disassembled,

please clean and check them, and replace
them with new ones if necessary.

----If the working surface of the brake disc wears

severely beyond the specified value (wearing
limit: 10.0mm), please replace it with a new
one.

Caution: Do not exceed the wearing limit.

----If the dust plate is severely deformed, please

replace it with a new one.

----If the hub spline wears severely and looses,

please replace it with a new one.

----If the spring retainer is not available, please

replace it with a new one.

----If the wheel bearing is damaged, please

replace it with a new one.

Installation and adjustment

----Set the outer spring retainer first, apply the

lubricating grease onto the wheel bearing
holder and then press the bearing down to the
limit position, as shown in the illustration,
and fix the inner spring retainer last.

----Adjust the split positions of the inner and

outer spring retainer so as to make their
difference 180°. Then rotate the bearing inner
