High-Pressure Monotube Shocks/New Front and
Rear Springs
The new variable-rate shocks and revised springs help to
create a suitable on-road ride without compromising
off-road competency. The shocks are designed to provide
improved stability, durability, and suspension articula-
tion.
Off-Road Tires
These tires are specifically designed for extreme off-road
use, while also maintaining quite on-road operation.The
tires utilize long-life compounds for increased durability,
and a deep-groove tread for extra traction. The LT285/
70R17D used provides a large contact patch for better
traction, two full-width steel belts for improved strength,
as well as a reinforced sidewall to help protect against
bruising and shredding.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components
of the truck including the fuel tank, transfer case and
steering damper. In addition the Power Wagon is
equipped with boxed cross membes and fore/aft rails.
This additional protection allows the vehicle to be uti-
lized in severe off-road situations that would be consid-
ered impassable by a normal truck.
Wheel Flares
Not just for looks, the wheel flares on the Power Wagon
were designed to help cover its new larger off-road tires.
The larger flares also help to reduce the amount of debris
that can be flung up by the more aggressive tread pattern
on the tires.

Stabilizer/Sway Bar System
Power Wagon vehicles are equipped with an electronic
disconnecting stabilizer/sway bar. This system allows
greater front suspension travel in off-road situations.
This system is controlled by the electronic control sway
bar switch located on the instrument panel.The switch has two positions, on-road and off-road. The
system is normally in on-road mode, indicated by a solid
green light. The stabilizer/sway bar should remain in
on-road mode during normal driving conditions.
WARNING!
Do not disconnect the stabilizer bar and drive on
hard surfaced roads or at speeds above 18 MPH, you
may lose control of the vehicle, which could result in
serious injury. The front stabilizer bar enhances
vehicle stability and is necessary for maintaining
control of the vehicle. The system monitors vehicle
speed and will attempt to reconnect the stabilizer bar
at speeds over 18 MPH. This is indicated by a
flashing off road light and solid on road light. Once
vehicle speed is reduced below 14 MPH the system
will once again attempt to return to off road mode.
Electronic Control Sway Bar Switch
234 STARTING AND OPERATING
To disconnect the stabilizer/sway bar, shift to either 4HI
or 4LO as shown in Four Wheel Drive Operation and
press the top of the stabilizer/sway bar button to obtain
the off-road position. The amber indicator light will flash
until the stabilizer/sway bar has been fully disconnected.
(See page 287 for more information.)
NOTE:The stabilizer/sway bar may be torque locked
due to left and right suspension height differences. This
condition is due to driving surface differences or vehicle
loading. In order for the stabilizer/sway bar to
disconnect/reconnect, the right and left halves of the bar
must be aligned. This alignment may require that the
vehicle be driven onto level ground or rocked from side
to side.
To return to on-road mode press the bottom of the
stabilizer/sway bar button.WARNING!
If stabilizer/sway bar will not return to on-road
mode, vehicle stability is greatly reduced. Do not
attempt to drive vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) may cause loss
of control of the vehicle, which could result in
serious injury. Contact your local service center for
assistance.

WARNING!
Winch cables are under high tension when in use
and can become a projectile if they fail. Never stand
over or straddle the winch cable. Never jerk or
overload the winch cable. Never stand in front of the
vehicle while winching. Failure to follow these in-
structions can result in serious or fatal injury.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After driving off-road, it is
always a good idea to check for damage.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard, or they might hide
damage to fuel lines, brake hoses, axle pinion seals,
and propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have brake drums and rotors,
brake linings, and axle yokes inspected and cleaned as
soon as possible.
•If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
packed material. Packed foreign material can cause a
wheel imbalance and cleaning the wheels will correct
the situation.

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
STARTING AND OPERATING 313

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
SUPPLEMENTAL TIRE PRESSURE INFORMATION
A light load vehicle condition is defined as two passen-
gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo.
Cold tire inflation pressures for a lightly loaded vehicle
will be found on the face of the driver’s door.
TIRE CHAINS
Use “Class U” chains on Power Wagon models, or other
traction aids that meet SAE Type “U” specifications.
NOTE:Chains must be the proper size for the vehicle,
as recommended by the chain manufacturer.
CAUTION!
To avoid damage to your vehicle, tires or chains, observe the
following precautions:
•Because of limited chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
vehicle damage. Stop the vehicle immediately if noise
occurs that could suggest chain breakage. Remove the
damaged parts of the chain before further use.
•Install chains as tightly as possible and then retighten after
driving about 1/2 mile (0.8 km).
•Do not exceed 45 mph (72 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•Do not install tire chains on front wheels of 4x2 vehicles.
•Do not drive for a prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on
method of installation, operating speed, and conditions for
usage. Always use the lower suggested operating speed of
the chain manufacturer if different than the speed recom-
mended by the manufacturer.

rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the
driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Label represents the actual tire size on
your vehicle. Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
