Follow these instructions to lower the spare tire:
1. If the vehicle is equipped with a hoist lock, open the
spare tire lock cover on the bumper and use the
ignition key to remove the lock.
2. Assemble the wheel wrench and the two jack handle
extensions as shown. Insert the hoist end (open end)
of the extension through the hole in the rear bumper.
Be sure the hoist end of the extension connects into
the hoist shaft (the ribbed square end of the
extension is used to lower the spare tire).
3. Turn the wheel wrench counterclockwise to lower
the spare tire to the ground. Continue to turn the
wheel wrench until the spare tire can be pulled out
from under the vehicle. The wheel wrench has a
hook that allows you to pull the hoist cable towards
you, to assist in reaching the spare tire.
4. When the tire has been lowered, tilt the retainer at
the end of the cable so it can be pulled up through
the wheel opening.
5. Put the spare tire near the flat tire.
The tools you'll be using include the bottle jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).
If the flat tire is on the rear of the vehicle, you'll need to
use both jack handle extensions.

Attach the wheel wrench to the jack handle extensions
(as needed). Attach the jack handle to the jack.Turn the wheel wrench clockwise to raise the jack lift
head to the lifting point.

If your vehicle has wheel
nut caps, loosen them by
turning the wheel wrench
counterclockwise. If you
have a center cap with
wheel nut caps, the wheel
nut caps are designed to
remain with the center cap.
Remove the center cap.
If the wheel has a smooth center piece, place the chisel
end of the wheel wrench in the slot on the wheel and
gently pry out.Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench
to loosen all the
wheel nuts. Turn the
wheel wrench
counterclockwise to
loosen the wheel nuts.
Don't remove the wheel
nuts yet.

2. Position the jack under the vehicle. If the flat tire
is on the front of the vehicle, position the jack on
the frame behind the flat tire where the frame
sections overlap.
On all 1500 series vehicles, use the jacking pad provided
on the rear axle. On 2500 series vehicles, use the axle
between the spring and shock.
If you have added a snow plow to the front of
your vehicle, lower the snow plow fully before raising
the vehicle.
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 fit the jack lift head
into the proper location before raising the vehicle.

3. Make sure the jack head is positioned so that the rear
axle is resting securely between the grooves that are
on the jack head. 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 fit back underneath the rear of the vehicle.

4. Remove all the wheel
nuts and take off the
flat tire.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the 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 the 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.
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.

6. After mounting
the spare, put the
wheel nuts back
on with the
rounded end of
the nuts toward
the wheel. Tighten
each wheel nut by
hand using the
wheel wrench until
the wheel is held
against the hub.
