2D – 20IREAR SUSPENSION
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
REAR SUSPENSION
The rear suspension is fully independent and consists of
a crossmember with four parallel links, two trailing links,
two strut assemblies with coil springs and insulators, and
two knuckles containing the hub and bearing assemblies.
The strut assemblies support the weight of the vehicle us-
ing coil springs positioned around the strut dampeners.The coil springs are seated on insulators attached to the
upper mount and the lower spring seat of the strut assem-
bly. The parallel links and the trailing link bracket have rub-
ber isolator bushings at each end and are attached to the
crossmember and the knuckle. The rear parallel link is at-
tached to the crossmember through adjustment cams that
are used to adjust rear toe. The trailing links are attached
to the body, through the trailing link bracket, and the bot-
tom of the knuckle. A forged knuckle bolts to each strut as-
sembly. Lateral movement of the knuckle is controlled by
the parallel links. Fore and aft movement of the knuckle is
controlled by the trailing link.

TIRES AND WHEELS 2E – 3

MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
WHEEL
Removal Procedure
1. Loosen the wheel bolts.
2. Raise and suitably support the vehicle.
3. Remove the wheel bolts.
Notice : Never use heat to loosen a tight wheel. It can
shorten the life of the wheel, the wheel nuts and the wheel
bearings. Excessive force, such as hammering the wheel
or tire, can also cause damage and is not recommended.
Slight tapping of the wheel sidewall with one’s hand or with
a rubber mallet is acceptable.
4. Remove the wheel.
Difficulty in removing the wheels from the vehicle can be
due to foreign material or to a tight fit between the wheel
centerhole and the hub or the rotor. These wheels can be
removed by
5. Retightening the wheel bolts on the affected wheel
and then loosening the wheel bolts by two turns.
6. Lowering the vehicle and rocking it from side to side
as hard as possible, using one or more person’s
body weight to loosen the wheel.
7. Raising the vehicle and removing the wheel.
CAUTION : Do not allow the penetrating oil to get on
the vertical surfaces between the wheel and the drum
(or rotor) because penetrating oil in this area could
cause the wheel to work loose as the vehicle is driven,
resulting in loss of control and an injury accident.
Penetrating oil is not effective in removing tight wheels. If
it is used, however, apply it sparingly and only to the
wheel’s centerhole area.
Installation Procedure
Notice : Before installing the wheels, remove any buildup
of corrosion on the wheel mounting surface and the brake
drum or the rotor mounting surface by scraping and brush-
ing them with a wire brush. Installing the wheels without
good metal–to–metal contact at the mounting surfaces
can cause the wheel nuts to loosen, which can later allow
a wheel to come off while the vehicle is moving. Wheel
bolts must be tightened in sequence and to the proper
torque to avoid bending the wheel, the brake drum or the
rotor.
1. Mount the wheel.
2. Install the wheel bolts in the sequence shown. Do
not tighten the wheel bolts.
3. Lower the vehicle.
Tighten
Tighten the wheel bolts to 100 NSm (74 lb–ft).
