wheel torque Oldsmobile Achieva 1998 Owner's Manuals

1. C! UTldN:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts.
If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere
as soon as you can and have the
nuts tightened with
a torque wrench to 100 lb-ft
(140 N-m).
NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
I NOTICE: I
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something
is wrong with
your brakes.
See “CaliperKnuckle Maintenance Inspection” in
Section
7 of this manual under Part C “Periodic
Maintenance Inspections.”
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires
are rotated, inspect
brake pads for wear and evenly torque wheel nuts in
the proper sequence to GM specifications.
Your rear drum brakes don’; have wear indicators, but if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected immediately. Also, the
rear
brake drums should be removed and inspected each time
the tires
are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then
-- very carefully -- make
a few moderate brake stops about every
1,000 miles
(1 600 km), so your brakes will adjust properly.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.

When It’s Time for New Tires Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that
all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth
or a paper towel to do this; but be
sure to
use a scraper or wire brush later, if you
need to, to get
all the rust or dirt off. (See
“Changing
a Flat Tire” in the Index.)
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire
if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged
The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other damage that
deep
enough to show cord or fabric.
can’t be repaired well because of the size or location
of the damage.
