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. The correct direction of rotation for dual tire
installations must also be observed. These dual rear wheels should be tightened as follows:
1. Tighten the wheel nuts in the numbered sequence to a
snug fit.
2. Retighten the wheel nuts in the same sequence to the
torques listed in the table. Go through the sequence a

WARNING! (Continued)
•Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
This inspection should be made with the vehicle in a level
position. The fluid level should be even with the bottom
of the fill hole for the manufacturer’s C205F HD frontaxles. The fluid level should be 5/8 in (16 mm) below the
fill hole on 9 1/4 in manufacturer’s rear axles.
For all 2500/3500 Model axles, the fluid level should be
1/4” ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on
the 9.25 in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on
10.5 in rear axles. The 11.5 in rear axle level should be
1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole.Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
NOTE:
The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.7

Limited-Slip Differentials
This vehicle requires that 4 oz. (118 ml) MOPARLimited
Slip Additive or equivalent be added to the gear lubri-
cant. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information. The
MOPAR Limited Slip Additive or equivalent should be
added to the gear lubricant whenever a fluid change is
made.
2500/3500 Model Axles DO NOT REQUIREany limited
slip oil additive (friction modifiers).
Transfer Case
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Automatic Transmission
Selection Of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only the manufacturer ’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. It is important that the transmission fluid be main-
tained at the prescribed level using the recommended
fluid.
