If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for im-
pacted material. Impacted foreign material can cause a
wheel imbalance. Removing the foreign material from
the wheels will correct the situation.
TRACTION
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front to avoid a collision in a sudden stop.
EQUIPMENT IDENTIFICATION PLATE
The equipment Identification Plate is located on the hood
inner surface.
The following information about your vehicle is dis-
played on this plate: Model, Wheelbase, Vehicle Identifi-
cation Number, Truck Order Number, and code numbers
with descriptions of all production and special equip-
ment on the truck as shipped from the factory.
NOTE:Always refer to the Equipment Identification
Plate When Ordering Parts.

WARNING!
The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes, unless suitable sup-
ports are placed under the vehicle as a safety mea-
sure. The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
WARNING!
After using the jack and tools, always reinstall them
in the original carrier and location. While driving
you may experience, abrupt stopping, rapid accelera-
tion, or sharp turns. A loose jack, tools, bracket or
other objects in the vehicle may move around with
force, resulting in serious injury.2500/3500 Model Vehicles

Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
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 ª4Lº 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.

back and forth motion, loosen the wheel skin. Repeat this
procedure around the tire until the skin pops off.
Replace the wheel skins first using a rubber mallet. When
replacing the hub caps, tilt the cap retainer over the
lugnut bolt circle and strike the high side down with a
rubber mallet. Be sure that the hub caps and wheel skins
are firmly seated around the wheel.
8-Stud Ð Dual Rear Wheels
Dual wheels are flat mounted, center piloted. The lug
nuts are a two piece assembly. When the tires are being
rotated or replaced, clean these lug nuts and add 2 drops
of oil at the interface between the hex and the washer.Slots in the wheels will assist in properly orienting the
inner and outer wheels. Align these slots when assem-
bling the wheels for best access to the tire valve on the
inner wheel. The tires of both dual wheels must be
completely off the ground when tightening to insure
wheel centering and maximum wheel clamping.

Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to cor-
rectly tighten the lug nuts. Also, when it is necessary to
remove and install dual rear wheels, use a proper vehicle
lifting device.
NOTE:When installing a spare tire as part of a dual rear
wheel end combination, the tire diameter of the two
individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front
location. Correct direction of rotation for dual tire instal-
lations must also be observed.
These dual rear wheels should be tightened as follows:

At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant bottle, brake master
cylinder, and transmission and add as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the CV joints (if equipped) and front suspen-
sion components.
²Check the automatic transmission fluid level.
²Check the manual transmission fluid level.
²Check the coolant level, hoses, and clamps.
Tire Rotation
²Rotate the tires at 6,000 miles (10 000 km).
