Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to remove
the at tire and raise the vehicle.
The tools you will be using include the jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).
1. Do a safety check before proceeding.
SeeChanging a Flat Tire on page 5-94
for more information.2. If your vehicle has
wheel nut caps, loosen
them by turning the
wheel wrench
counterclockwise.
If the vehicle has a center cap with wheel nut caps,
the wheel nut caps are designed to stay with the
center cap after they are loosened. Remove
the entire center cap.
5-100

If the wheel has a smooth center cap, place the
chisel end of the wheel wrench in the slot on
the wheel, and gently pry it out.3. Use the wheel wrench and turn it counterclockwise
to loosen the wheel nuts. Do not remove the wheel
nuts yet.
5-101

If the at tire is on the rear, position the jack under
the rear axle between the spring anchor and the
shock absorber bracket.
If you have added a snow plow to the front of your
vehicle, lower the snow plow fully before raising
the vehicle.
Make sure that the jack head is positioned so that
the rear axle is resting securely between the
grooves that are on the jack head.
{CAUTION:
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.
{CAUTION:
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 t the
jack lift head into the proper location before
raising the vehicle.
5. Turn the wheel wrench clockwise to raise the
vehicle. Raise the vehicle far enough off the ground
so there is enough room for the spare tire to t
under the wheel well. Rear Position – All Models
5-103

11. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
{CAUTION:
Incorrect or improperly tightened wheel nuts
can cause the wheel to come loose and
even come off. This could lead to a crash.
If you have to replace them, be sure to
get new original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-133for wheel nut
torque specication.
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 specication. SeeCapacities and
Specifications on page 5-133for the wheel nut
torque specication.12. Tighten the nuts rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap, or bolt-on hub
cap, depending on what your vehicle is equipped with.
For center caps, place the cap on the wheel and
tap it into place until it seats ush with the wheel.
The cap only goes on one way. Be sure to line up the
tab on the center cap with the indentation on the wheel.
For bolt-on hub caps, align the plastic nut caps with
the wheel nuts and then tighten by hand. Then use the
wheel wrench to tighten.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work,
the spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools on
page 5-110.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed next.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not
visible proceed
to Step 6.
2. If it is visible, rst 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 wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times. If the
spare tire lowers to the ground, continue with
Step 5 ofRemoving the Spare Tire and Tools
on page 5-95.
5. If the spare does not lower, turn the wrench
counterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
5-106

6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom edge
of the jack (A) on the
wheel blocks (B),
separating them so that
the jack is balanced
securely.
8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the
rear bumper.
5-107

9. Position the center lift point of the jack under the
center of the spare tire.
10. Turn the wrench clockwise to raise the jack until it
lifts the end tting.11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place.
The secondary latch has released and the spare
tire is balancing on the jack.
12. 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.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack.
If the spare tire does not slide off the jack
completely, make sure no one is behind you or
on either side of you as you pull the jack out
from under the spare.
5-108

13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while rmly pulling the jack
out from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert the
hoist end of extension, and wheel wrench into
the hoist shaft hole in the bumper and turn
the wheel wrench counterclockwise to lower the
spare the rest of the way.
14. Tilt the tire retainer at the end of the cable and pull
it through the wheel opening. Pull the tire out from
under the vehicle.
15. Turn the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up if the
cable is hanging under the vehicle.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or at tire using
the hoist assembly until it has been replaced.
