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.

pacity, diameter, rim width, offset, and mounting configu-
ration. A wheel of improper size or type may affect wheel
and bearing life, brake cooling, speedometer/odometer
calibration, vehicle ground clearance, and tire clearance
to the body and the chassis. The wheel offset is 49 ± 1 mm
(1.93 ± 0.04 inches). Steel wheels may be identified by a
two– or three–letter code stamped into the rim near the
valve stem. Alloy wheels should have the code, the part
number, and the manufacturer ID cast into the back side.
INFLATION O TIRES
The pressure recommended for any vehicle line is careful-
ly calculated to give a satisfactory ride, handling, tread life,
and load–carrying capacity.
Tire pressure should be checked monthly or before any
extended trip. Check the tires when they are cold, after the
vehicle has sat for 3 hours or more, or has been driven less
than 1 mile. Set the tire pressure to the specifications on
the tire label located on the rear face of the driver’s door.
Tire inflation pressure is also given under ”Tire Size and
Pressure Specifications” in this section.
Valve caps or extensions should be on the valves to keep
dust and water out.
For sustained driving at speeds up to 140 km/h (85 mph),
inflate the tires to the pressure recommended on the tire.
Sustained driving at speeds faster than 140 km/h (85mph), even if permitted by law, is not advised unless the
vehicle has special high–speed tires available from many
tire dealers. Tire pressures may increase as much as 41
kPa (6 psi) when the tires are hot.
Higher than recommended tire pressure can cause
S Hard ride.
S Tire bruising or damage.
S Rapid tread wear at the center of the tire.
Lower than recommended pressure can cause
S Tire squeal on turns.
S Hard steering.
S Rapid and uneven wear on the edges of the tread.
S Tire rim bruises and rupture.
S Tire cord breakage.
S High tire temperatures.
Unequal tire pressures on same axle can cause
S Uneven braking.
S Steering lead.
S Reduced handling.
S Swerve on acceleration.
S Torque steer.

hose or the unthreaded adapter cap, cover the cap and the
connection with a shop towel to protect painted surfaces
from contact with the brake fluid.
