POWER WAGON FEATURES
Locking Front and Rear Differentials
Most 4WD trucks are equipped with open differentials
front and rear. This design is used because it allows each
wheel to turn independently helping to eliminate bind-
ing when cornering. A disadvantage of using an open
differential is when one or more wheels lose traction; all
of the power is directed to those wheels resulting in a loss
of momentum. The Power Wagon is equipped with
electronically locking front and rear differentials. These
differentials, when engaged, mechanically lock together
the axle shafts forcing the wheels to spin at an equal rate.
This allows the vehicle to maintain its momentum and
thus prevents it from becoming stuck. The locking front
and rear differentials should only be engaged during
low-speed, extreme off-road situations where one wheel
is likely to not be in contact with the ground. It is notrecommended to drive the vehicle with the differentials
locked on pavement due to the reduced ability to turn
and speed limitations.
4.56:1 Gears
This is the highest axle ratio available in a full-size
pickup. The high gearing helps to compensate for the
increased rolling mass and increase diameter of the
off-road tires. As well, there are many advantages to a
higher axle ratio in off-road applications. When driving
downhill the high gearing enables the driver to use the
engine to slow the vehicle down in a more controlled
manner. When driving up a steep grade, the ratio helps
by keeping the truck in its power band helping to
maintain upward momentum.

Wheels
Stylish forged aluminum 17wheels give the Power
Wagon a powerful stance. Forging a wheel from alumi-
num produces a stronger, lighter weight wheel than
machining or casting the wheel out of the same material.
Standard package features:
•
Fuel Tank Skid Plate - protects the fuel tank from
impingement damage.
•Transfer Case Skid Plate and Tubing - protects the
transfer case and exhaust catalyst from impingement
damage.
•Heavy Duty Cross Members - protects the under
carriage and supports the under body protection skid
plates.
•Fore/Aft rails - which connect the cross member for
additional support and prevent the truck from getting
hung up on large rocks between the cross members.
•Steering Dampener Skid Plate - protects the steering
dampener from impingement damage.
•Electronically Locking Front And Rear Axle Differen-
tials With 4:56 Gears - improves mobility and articu-
lation by locking the differentials.
•Electronically Disconnecting Stabilizer/Sway Bar - im-
proves mobility and articulation by disconnecting the
Stabilizer/Sway Bar.
•160 Amp Alternator - supplies increased electrical
power for the winch and other off-road accessories.
•Heavy Duty Battery - supplies increased electrical
power for the winch and other off-road accessories.
•Heavy Duty Cooling Fan - provides enhanced engine
and transmission cooling under vigorous off-road
conditions.

•Off-Road Tuned Suspension And Shocks - improves
mobility, ground clearance and ride comfort.
•Heavy Duty Thermally Protected and Sealed Electric
Winch With Roller Fairlead - Useful for work and
vehicle recovery.
•17 Inch Forged Aluminum Wheels With 33 Inch Tires
- improves traction and differential ground clearance.
Mopar Options:
•
Rock Rails - protects the door sills from impingement
damage and provides a vehicle jacking point.
•Winch accessory kit - Contents include:
•Snatch Block/Pulley
•Clevis
•Tree strap
•Tow Strap
•Gloves
•“Power Wagon embossed”storage bag
•Bed Liner - protects the bed from impingement dam-
age
NOTE:These Mopar options have been specially de-
signed and tested for the Power Wagon to meet the
vigorous off-road conditions.
MIRRORS
Inside Mirror
The mirror should be adjusted to center on the view
through the rear window.
Annoying headlight glare can be reduced by moving the
small control under the mirror to the night position
(toward rear of vehicle). The mirror should be adjusted
while set in the day position (toward windshield).

216 STARTING AND OPERATING

The switch has three positions, UNLOCK, RR, and FR/
RR. Under normal driving conditions the switch should
be left in the UNLOCK position. In the UNLOCK posi-
tion, the front and rear axles are unlocked. In the RR
position, the rear axle is locked. In the FR/RR position,
the front and rear axles are locked.NOTE:Even when the axles are in the UNLOCK
position, the limited slip differential in the rear axle still
provides torque biasing capability for moderate low
traction environments.
During the command to lock the axle, the indicator light
will flash until the axle is locked. After the lock command
has been successfully executed, the light will remain on
solid.
To lock the rear axle, place the vehicle in 4LO by
following the procedure in Four Wheel Drive Operation,
located in this section of the manual. Move the axle
locker switch position to RR while travelingless than 3
MPH (5 KM/H). The RR indicator light will remain on
when the rear axle is locked.

Water Fording Characteristics
Water fording characteristic is the vehicle’s ability to
cross a body of still water, where the powertrain and
drivetrain are safe from water ingestion. The Power
Wagon has high water fording characteristics with the
ability to cross a pool of water, without stopping, 24
inches deep at a maximum speed of 10 mph and a pool of
water 30 inches deep at a maximum speed of 5 mph, both
with an entrance ramp angle of 1.3 degrees.
CAUTION!
The door sill height is 25 inches. Water may intrude
into the interior of the vehicle at greater depths.

228 STARTING AND OPERATING

Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only be
attempted when necessary, in a safe responsible manner.
You should only drive through areas which are desig-
nated and approved. You should tread lightly and avoid
damage to the environment. You should know your
vehicles abilities and be able to recover it if something
goes wrong. You should never stop or shut a vehicle off
when crossing deep water unless you ingested water into
the engine air intake. If the engine stalls do not attempt to
restart it. Determine if it has ingested water first. The key
to any crossing is low and slow. You want to use 1st gear
in 4L (low) and proceed very slowly with a constant slow
speed (3-5 mph maximum) and light throttle. Keep the
vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, you should inspect all of the
vehicle fluids for signs of water ingestion.CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can cause
permanent damage to engine, driveline or other
vehicle components and your brakes will be less
effective once wet and/or muddy
•Before You Cross Any Type Of Water–As you
approach any type of water you need to determine if
you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a
stick. You need to be sure of its depth, approach angle,
current and bottom condition. Be careful of murky or
muddy waters, check for hidden obstacles. Make sure
you will not be intruding on any wildlife and you can
recover the vehicle if necessary. The key to a safe
