2004 DAEWOO NUBIRA shock absorber

FRONT SUSPENSION 2C – 5
DAEWOO V–121 BL4
DIAGNOSIS
STRUT DAMPENER
A strut dampener is basically a shock absorber. However, strut dampeners are easier to extend and retract by hand than
are shock absorbers.
Struts Seem Weak
ChecksAction
Check the tire pressures.Adjust the tire pressures to the specifications on the tire
placard.
Check the load conditions under which the vehicle is nor-
mally driven.Consult with the owner to confirm the owner’s understand-
ing of normal load conditions.
Check the compression and rebound effectiveness of the
strut dampener.Quickly push down and then lift up on the corner of the
bumper nearest the strut dampener being tested.
Compare the compression and rebound with those of a
similar vehicle that has an acceptable ride quality.
Replace the strut dampener, if needed.
Struts Are Noisy
ChecksAction
Check the mountings for looseness or damage.Tighten the strut dampener mounting nuts. Replace the
strut dampener, if needed.
Check the compression and rebound effectiveness of the
strut dampener.Quickly push down and then lift up on the corner of the
bumper nearest the strut dampener being tested.
Compare the compression and rebound with those of a
similar vehicle that has an acceptable ride quality.
Replace the strut dampener, if needed.
Leaks
ChecksAction
Check for a slight trace of fluid.The strut dampener is OK.
Check the integrity of the seal cover on the fully extended
strut.Replace the strut dampener.
Check for an excessive amount of fluid on the strut damp-
ener.Replace the strut dampener.

REAR SUSPENSION 2D – 3
DAEWOO V–121 BL4
DIAGNOSIS
EXCESSIVE FRICTION CHECK
Check excessive friction in the rear suspension as follows:
1. With the aid of a helper, lift up on the rear bumper
and raise the vehicle as high as possible. Slowly
release the bumper and allow the car to assume
normal trim height.
2. Measure the distance from the floor to the center of
the bumper.
3. Push down on the bumper, release slowly, and al-
low the car to assume normal trim height.4. Measure the distance from the floor to the center of
the bumper.
The difference between the two measurements should be
less than 12.7 mm (0.50 inch). If the difference exceeds
this limit, inspect the control arms for damage or wear.

2. FRONT WHEELHOUSE
2–1. GENERAL DESCRIPTION
The front wheelhouse component is constructed as a
unit with the locator shockabsorber. Therefore, replace-
ment of the component affects the front wheel align-ment. When assembling it, either use a jig or follow di-
mensions on the body repair chart for positioning. It
must be welded carefully.
