2D – 2 REAR SUSPENSION
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
REAR SUSPENSION
The rear suspension consists of an axle with trailing
arms and a lateral rod, two coil springs, two shock ab-
sorbers, two upper spring seats, and two bump stop-pers. The axle structure maintains the relationship of the
wheels to the body.
Each coil spring is retained between a seat in the under-
body and a seat welded to the top of the rear axle.

REAR AXLE ASSEMBLY
(INCLUDING COIL SPRING)
Removal Procedure
1. Remove the rear brake drum, shoe and brake plate.
Refer to Section 4E, Rear Drum Brakes.
2. Remove the lateral rod. Refer to “Lateral Rod” in this
section.
3. Disconnect the rear axle and the trailing arm.

Support the rear axle with adjustable jack stands
(1).

WHEEL
Removal Procedure
1. Remove the wheel cover on the vehicle equipped
with steel wheel.
2. Loosen the wheel nuts.
3. Raise and suitably support the vehicle.
4. Remove the wheel nuts.
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 rec-
ommended. Slight tapping of the wheel sidewall with
one’s hand or with a rubber mallet is acceptable.
5. 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
1. Retightening the wheel nuts on the affected wheel
and then loosening the wheel nuts by two turns.
2. 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.
3. 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.
