Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the “4L” position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.

Instructions
WARNING!
Carefully follow these tire changing warnings to help
prevent personal injury or damage to your vehicle:
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Apply the parking brake firmly before jacking.
•Never start the engine with the vehicle on a jack.
•Do not let anyone sit in the vehicle when it is on
a jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated.
•If working on or near a roadway, be extremely
careful of motor traffic.
1. Remove the spare wheel, jack, and tools from storage.
2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
3. For 2500/3500 4x2 series trucks, when changing a
front wheel, place the bottle jack under the frame rail
behind the wheel. Locate the jack as far forward as
possible on the straight part of the frame.
For 2500/3500 4x4 series trucks, when changing the front
wheel, assemble the jack drive tube to the jack and
connect the drive tube to the extension tube. Place the
jack under the axle as close to the tire as possible with the
drive tubes extending to the front. Connect the jack tube
extension and wheel wrench.
When changing a rear wheel, assemble the jack drive tube
to the jack and connect the drive tube to the extension
tube. Place the jack under the axle between the spring and
the shock absorber with the drive tubes extending to the
rear. Connect the jack tube extension and wheel wrench.

Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE:If the jack will not lower by turning the dial
(thumb wheel) by hand, it may be necessary to use the
jack drive tube in order to lower the jack.

Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
HOISTING
A conventional floor jack may be used at the jacking
locations, refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from battery
vent holes. Always wear eye protection when work-
ing with batteries.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. do
not use a 24 volt power source.
NOTE:Replacement batteries should both be of equal
size to prevent damage to the vehicles charging system.
