wheel Oldsmobile Bravada 2003 s Repair Manual

A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle
to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake
to a stop - well off the road if possible.
If
a tire goes flat, the next part shows how to use your
jacking equipment
to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly
to a level place. Turn on your
hazard warning flashers. Cha..,ing
a tire can ca-.-e an injc.
,. The
vehicle can slip
off the jack and roll over you
or other people. You and they could be badly
injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
4. Put the wheel blocks at the front and rear
of the tire farthest away from the one
being changed. That would be the tire on
the other side of the vehicle,
at the
opposite end.

The tools you'll be using include the wheel wrench (A),
tire blocks (B), extension (socket end) (C), handle
(jack end)
(D), and jack (E).
The following instructions explain how to remove the
spare tire mounted underneath your vehicle.
Notice: Never remove or restow a tire from/to a
storage position under the vehicle while the vehicle
is supported by a jack. Always tighten the tire
fully against the underside
of the vehicle when
restowing.

1. To remove the underbody-mounted spare, insert
the socket end of the extension on a
45" angle
downward into the hoist drive shaft hole. This will
be exposed when the rear gate is open and is
just above the rear bumper. Be sure the socket end
of the extension connects into the hoist shaft.

2. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench until
the spare tire can be pulled out from under the
vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. See “Secondary Latch System” later in
this section.
When the tire has been completely lowered, tilt the
retainer at the end of the cable and pull it through
the wheel opening. Pull the tire out from under
the vehicle.
Notice:
To help avoid vehicle damage, do not drive
the vehicle before the cable is restored.
3. Put the spare tire near the flat tire.
4. Position the chisel end of
your wheel wrench in the
notch of the center
cap and pry
off the
center cap.
See “Removing the Flat Tire and Installing the Spare
Tire” later in this section to continue changing the flat tire.

1. Check under the vehicle
to see
if the cable is
visible.
2. If it is not visible, proceed to Step 6.
If visible, first try to tighten the cable by turning the
wheel wrench clockwise until you hear two clicks
or feel it skip twice. You cannot overtighten
the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground, continue with

approximately
6 inches (15 cm) of cable is exposed.
5. Turn the wrench counterclockwise until
6. Attach the jack handle, extension and the wheel
wrench to the jack and place it under the vehicle
towards the front of the rear bumper. Position
the center lift point of the jack under the center of
the spare tire.
7. Turn the wrench clockwise to raise the jack until it
lifts the end fitting.
8. Continue raising the jack until the spare tire stops
moving upward and is held firmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.

10. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until the
spare tire slides
off the jack or is hanging by
the cable.
Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert the
jack handle, extension and wheel wrench into the
hoist shaft hole in the bumper, on an angle, and turn
the wheel wrench counterclockwise
to lower the
spare the rest of the way.
11. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
12. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using
the hoist assembly until it has been repaired or replaced.

4. Place the jack
in the appropriate position nearest
the flat tire.
Getting under a vehicle when
it is jacked up is
dangerous. If the vehicle slips
off the jack you
could be badly injured or killed. Never get under
a vehicle when it
is supported only by a jack. Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle
fall.
To help avoid personal
injury and vehicle damage, be sure to
fit the
jack lift head into the proper location before raising the vehicle.

Incorrect wheel nuts or improperly tightened

CAUTION: (Continued) Stop somewhere as soon
as you can and have
the nuts tightened with a torque wrench to the
proper torque specification. See “Capacities

Notice: Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel

Storing 9 Flat or Spare Tire and Tmls
n
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury.
In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
.
The underbody-mounted spare tire needs to be
stored with the valve stem pointing up. If the
spare tire is stored with the valve stem
pointing downward,
its secondary latch won’t
work properly and the spare tire could loosen

and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the underbody-
mounted spare tire
is stored with its valve
stem pointing up.
Notice: An aluminum wheel with a flat tire should
always be stored under the vehicle with the hoist. However, storing
it that way for an extended
period could damage the wheel. To avoid this,
always stow the wheel properly with the valve stem
pointing up and have the wheel repaired as soon
as possible.
Follow this diagram to store the underbody-mounted
spare.
