Be sure the hoist end (J) of the extension (D)
connects to the hoist shaft (B). The ribbed square
end of the extension is used to lower the spare tire.
5. Turn the wheel wrench (E) counterclockwise to lower the spare tire (H) to the ground. Continue to
turn 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
on page 6‑101for more information.

Front Position–1500 ModelsFront Position –2500 Models
Front Tire Flat: If the flat tire is on a front tire of
the vehicle, you will need to use the jack handle
and only one jack handle extension. Attach the
wheel wrench to the jack handle extension. Attach
the jack handle to the jack (A). Position the jack
on the frame behind the flat tire where the frame
sections overlap. 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 clear the ground.

Rear Position–1500 ModelsRear Position –All Other Models
Rear Tire Flat: If the flat tire is on a rear
tire of the vehicle, you will need to use
the jack handle (B) and both jack handle
extensions (C). Attach the wheel wrench (D)

page 6‑125
for original equipment wheel nut
torque specifications.
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. See Capacities and
Specifications
on page 6‑125for the wheel nut
torque specification.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap or the bolt-on hub
cap, depending on which your vehicle has.
.For center caps, line up the tab on the center cap
with the slot in the wheel. The cap only goes in
one way. Place the cap on the wheel and press
until it snaps into place.
.For bolt-on hub caps, line up the plastic nut caps
with the wheel nuts and tighten clockwise by hand
to get them started. Then tighten with the wheel
wrench until snug.

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 6‑104.
{WARNING:
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, 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 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 of Removing the Spare Tire and Tools
on
page 6‑89.

5. If the spare does not lower, turn the wrenchcounterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends, with the backs facing each other.
7. Place the bottomedge 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 wheelwrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the
rear bumper.

9. Position the center lift point of the jack under thecenter of the spare tire.
10. Turn the wrench clockwise to raise the jack until it lifts the end fitting.
11. 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.
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.
{WARNING:
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.
13. 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 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. 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 flat tire using
the hoist assembly until it has been inspected and/or
replaced.
To continue changing the flat tire, see Removing the
Flat Tire and Installing the Spare Tire on page 6‑94.
