wheel torque PONTIAC GRAND AM 1998 Owners Manual

10. Tighten the wheel nuts
firmly in a crisscross
sequence, as shown.
' A CAUTION: I I
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).
I 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:
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.

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake
pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you
are pushing on the brake pedal firmly).
A
a CAUTION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake
wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
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’t 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.”

x
When rotating your tires, always use the correct rotation
pattern shown here.
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.
P
CAUTION:
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.)
