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.

Installation Procedure
Notice: Before installing the wheels, remove any build-
up of corrosion on the wheel mounting surface and the
brake drum or the rotor mounting surface by scraping
and brushing 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 ve-
hicle is moving. Wheel nuts must be tightened in se-
quence and to the proper torque to avoid bending the
wheel, the brake drum or the rotor.
1. Mount the wheel.
2. Install the wheel nuts in the diagonally. Do not tighten
the wheel nuts.
3. Lower the vehicle.
Tighten
Tighten the wheel nuts to 90–110 Nm (66–81 lb-ft).
ON-VEHICLE BALANCING
On-vehicle balancing will help correct vibrations due to
brake drum, rotor, and wheel cover imbalances.
Notice: Do not allow the front suspension to hang free.
When the drive axle is run at an extreme angle, extra
vibrations can occur, as well as damage to seals and
joints.
1. During on-vehicle balancing, do not remove the bal-
ance weights from the off-vehicle dynamic balance.
2. If more than 1 ounce of additional weight is required,
split the weight between the inner and the outer rim
flanges.
3. Spin the driven tire and wheel assemblies using the
engine.
OFF-VEHICLE BALANCING
Perform wheel balancing with an electronic off-vehicle
balancer. The balancer is easy to use and gives both a
static and a dynamic balance. Unlike on-vehicle balanc-
ing, the off-vehicle balancer does not correct for drum or
rotor imbalance. This drawback is overcome by its accu-
racy. Secure the wheel on the balancer with a cone
through the back side of the centerhole, not through the
wheel nut holes.
CORRECTING NON-UNIFORM TIRES
There are two ways to correct properly balanced tires
which still vibrate. One method uses an automatic
machine which loads the tire and buffs small amounts of
rubber from high spots on the outer two tread rows.
Correction by this method is usually permanent and, if it
is done properly, does not significantly affect the
appearance or the tread life of the tire. Tire truing with a
blade-type machine is not recommended because it
substantially reduces the tread life and often does not
correct the problem permanently.

TIRES AND WHEELS 2E–9
DAEWOO M-150 BL2
Another method is to dismount the tire and rotate it
180 degrees on the rim. Do this only on the tire and
wheel assemblies which are known to be causing a
vibration because this method is just as likely to cause
good assemblies to vibrate.
TIRE AND WHEEL
MATCH-MOUNTING
The tires and wheels are match-mounted at the assem-
bly plant. Match-mounting aligns the radially stiffest part
of the tire, or high spot, to the smallest radius, or low
spot, of the wheel.
The high spot of the tire is originally marked by a red
paint mark or an adhesive label on the outboard side-
wall.
The low spot of the wheel will be at the location of the
valve stem.
Before dismounting a tire from its wheel, scribe a line on
the tire at the valve stem to assure that it is remounted in
the same position.
Replacement tires that are of original equipment quality
will have their high and low spot marked in the same
manner.

3B – 2 MANUAL TRANSAXLE DRIVE AXLE
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
FRONT DRIVE AXLE
Drive axles are flexible shaft assemblies that transmit a
rotational force from the transaxle to the front wheel as-
semblies. Each axle assembly consists of an inner
constant-velocity joint and an outer constant-velocity
joint connected to an axle shaft. The inner joint is com-pletely flexible and has the ability to move in and out.
The outer joint is also flexible, but it cannot move in and
out.
The drive axles use a Rzeppa–style joint on the out-
board side and a Tripot–style joint on the inboard side.
