Chery A15 / 480 LHD model. Manual — part 17

FRONT SUSPENSION

The functions of axle and suspension system include receiving the torque generated by
engine and passed via transmission system; producing the traction force between the road
surface and the vehicle body through the adhesive force between the driving wheel and the
ground in order to keep the whole vehicle steering normally; passing and bearing the
counterforce on the wheel from different directions and relieving the impact and shake from
the road to the vehicle body in order to ensure the stability and maneuverability of the whole
vehicle. The front suspension is composed of the sub-frame, lateral stabilizer bar, control arm
and etc.

REMOVAL AND INSTALLATION OF THE FRONT SUSPENSION

----Loosen the opening of the joint bracket of

the front shock absorber assy and clip it
to the bolt of the steering knuckle
arm(tightening the lock nut to 80N•m),
(shown as the picture)

----Remove the joint bolt of the control arm

assy and the front steering knuckle with
braker, and then release the front control
arm assy.

Inspection of the control arm: check the
situations of the damage crack and bend.

----Loosen the four bolts amounted on the

sub-frame of the steering gear with tie rod
assy (the specified tightening torque is
30N•m). (shown as the picture)

----Suspend the engine and transmission assy,

loosen the bolts at the two supporting
points from the engine and transmission
to the sub-frame.

Caution: The removal process is extremely
dangerous which could cause serious
damage or even death. Please make sure the
power assy is well fixed.

----Loosen the lock nut of the left-right

steering tie rod and the steering knuckle
arm, knock from one side to pry the ball
joint out of the steering knuckle arm (The
tightening torque is specified as 35±3
N·m).

----Stand the front sub-frame by jack and

loosen the four long-short bolts of the left
-right sub-frame with the cross beam.
(The tightening torque is specified as
130±10 N·m).

Caution: The removal of the cross beam is
extremely dangerous. The drop of cross
beam components could cause serious
damage or even death. Please make sure
that the jack has supported fully the cross
beam components before the removal.

OVERHAUL OF THE FRONT SUSPENSION

Installation of the front axle

Cherry adopts the divided steering drive axle as
the front axle. The suspension is the model of
shock absorber (also called MacPherson)
independent suspension. The front suspension
of A15RHD model has the functions of both
driving and steering. The top of the suspension
is connected with the vehicle body while the
bottom with the steering knuckle. The wheel
camber is adjusted through the joint bolt of the
suspension the steering knuckle. The sub-frame
enhances the stability and comfortability of the
vehicle through the connection of the control
arm ball pin and the hinge by adopting the
elastic components.

Overhaul of the front suspension

----When overhaul the front suspension, please

do not weld or remodel the support and
guide devices of the front suspension.

----Use the special purpose tools to remove the

joint bolts or nuts. Make sure the
tightening torque fits the specified value.

----When install the sub-frame to the vehicle

body, the sequence of tightening the joint
bolts is the rear left bolt, the rear right
bolt, the front left bolt and the front right
bolt last.

----Check the position of steering wheel and

measure the data of front wheel
alignment after installation.

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.
