FRONT SUSPENSION 2C – 25
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
FRONT SUSPENSION
The front suspension for this vehicle is a combination of
a strut assembly and a knuckle assembly. The strut as-
sembly combines a strut dampener and spring mounted
to the body of the vehicle. The upper end of the strut is iso-
lated by a rubber mount and contains a bearing to allow the
strut to turn. The knuckle is attached to the strut assembly
and pivots on a ball joint bolted to the control arm. The con-
trol arms pivot from the body using rubber bushings.
The ball joint is fastened to the steering knuckle with a
pinch bolt and nut, and to the lower control arm with rivets.
The stabilizer bar interconnects both strut assemblies ofthe vehicle through the stabilizer link and is attached to the
front suspension crossmember. Jounce and rebound
movements affecting one wheel are partially transmitted
to the opposite wheel of the vehicle to stabilize body roll.
When servicing the control arm–to–body attachment and
the stabilizer shaft–to–body insulators, make sure the at-
taching bolts are loose until the control arms are moved to
the trim height, which is curb height. Trim height is the nor-
mal position to which the control arms move when the ve-
hicle is sitting on the ground. Refer to ”General Specifica-
tions” in this section.
The springs in the front suspension of engine family II are
stronger and the strut dampeners heavier than are the
springs and strut dampeners found in the front suspension
of engine family I.

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 vibra-
tions can occur, as well as damage to seals and joints.
1. During on–vehicle balancing, do not remove the
balance weights from the off–vehicle dynamic bal-
ance.
2. If more than 1 ounce of additional weight is re-
quired, split the weight between the inner and the
outer rim flanges.
CAUTION : Do not spin the drive wheels faster than
55km/h (35 mph) as indicated by the speedometer.
This limit is necessary because the speedometer indi-
cates only one–half of the actual wheel speed when
one drive wheel is spinning and the other drive wheel
is stopped. Personal injury and damage may result
from high–speed spinning.
3. Spin the driven tire and wheel assemblies using the
engine.

Before repairing the alloy damage or the clear coat dam-
age, prepare the wheels and the tires.
1. Remove the wheel from the vehicle.
2. Mark the location of the outboard weights and re-
move them.
3. Wash the wheel inside and out with a water–based,
all–purpose cleaner. Remove the grease and oil
with a solvent cleaner.
4. Mask the tire prior to painting.
5. Using a 400–grit wet or dry sandpaper, sand over
the painted areas that will not require recoloring.
Sanding will promote the adhesion of the clear coat.
Alloy Damage on Wheel Surface
1. Mount the wheel on a brake lathe and spin the as-
sembly slowly.
2. Sand the wheel with a backing block or pad. Hold
the backing block or pad flat to the surface of the
wheel and sand slowly back and forth from the cen-
ter to the outer edge of the tire to remove the dam-
age. Use the following sandpaper grits in the order
listed:
1) 80 grit.
2) 150 grit.
3) 240 grit.
Clear Coat Damage on Unpainted Wheels
1. Apply the chemical stripper Amchem Alumi Prep
No. 33. Use a small 1/4–inch detail brush to apply
the stripper around the perimeter and spoke–like
areas.
2. Remove the stripper according to the manufactur-
er’s recommendations.
CAUTION : To avoid serious personal injury, do not
use engine power to rotate the wheel while sanding.
3. Sand the wheel with 240–grit sandpaper by rotating
the wheel on a slow–spinning brake lathe or by
mounting the wheel on the car and spinning it by
hand. Sanding restores the machined appearance
and promotes adhesion.
After repairing the alloy or clear coat damage, the wheels
must be recoated.
