CAUTION!
Towing faster than 30 mph (50 km/h) or for more
than 15 miles (25 km) can cause severe damage to the
transmission.
If the vehicle is to be towed more than 15 miles (25 km)
the vehicle must be towed with the rear wheels raised
and the front wheels on the ground. It may also be towed
on a flatbed or with the front wheels raised and the rear
wheels on a dolly.

Steering Linkage — Inspection
Whenever the vehicle is hoisted, all steering linkage
joints should be inspected for evidence of damage. If
seals are damaged, parts should be replaced to prevent
leakage or contamination of the grease. Lubricate the
steering linkage regularly according to the “Maintenance
Schedule” in this manual.
Half-shaft Constant Velocity Joints
All four- wheel- drive 1500 models are equipped with
four constant velocity joints. Periodic lubrication of these
joints is not required. However, the joint boots should be
inspected for external leakage or damage periodically. If
external leakage or damage is evident, the joint boot and
grease should be replaced immediately. Continued op-
eration could result in failure of the joint due to water
and dirt contamination of the grease. This would require
complete replacement of the joint assembly. Refer to the
Service Manual for the detailed replacement procedure.
Front Prop Shaft Lubrication — 2500/3500 (4X4)
Models
Lubricate the front driveshaft grease fitting at each oil
change listed in the appropriate Maintenance Schedule
for your vehicle (Schedule “A” and “B”). Use Mopar
type MS-6560 (lithium based grease), or equivalent.

Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
“purge” excess grease and the bearing will look slightly
wet. This is normal. Periodic inspection for excess play is
recommended.
Rear Wheel Bearings — Manufacturer’s Axles
These bearings are normally considered permanently
lubricated. Cleaning and repacking is required only
when axle shafts are removed or in case of extreme water
or dust contamination.
Selection of Lubricating Grease
The National Lubricating Grease Institute (NLGI) has
developed a symbol (Certification Mark) to aid the
vehicle owner in the proper selection of grease for the
lubrication of wheel bearings and chassis components.This symbol (an example is shown below) is located on
the grease container and identifies the application and
quality of the grease.
There are two groups
identified, those for wheel
bearings (Letter “G”) and
those for chassis (Letter
“L”) lubrication. Perfor-
mance categories within
these groups result in dual
letter designations for
each group. The letter des-
ignations shown in the ex-
ample are the highest
quality level available and when combined as shown can
be used for both wheel bearing and chassis lubrication.
Use only those greases that have the NLGI symbol on the
container along with the proper quality level for your
application.

Noise Control System Required Maintenance &
Warranty For 3500 2-Wheel Drive and 4-Wheel
Drive models over 10,000 lbs. (4 535 kg) Gross
Vehicle Weight Rating.
All vehicles built over 10,000 lbs (4 535 kg) Gross Vehicle
Weight Rating and manufactured for sale and use in the
United States are required to comply with the Federal
Government’s Exterior Noise Regulations. These vehicles
can be identified by the Noise Emission Control Label
located in the operator’s compartment.

•If your vehicle is damaged due to an accident or
similar cause which destroys the paint and protective
coating have your vehicle repaired as soon as possible.
The cost of such repairs is considered the responsibil-
ity of the owner.
•All wheels and wheel trim, especially aluminum and
chrome plated wheels should be cleaned regularly
with mild soap and water to prevent corrosion. To
remove heavy soil, select a nonabrasive, non-acidic
cleaner. Do not use scouring pads, steel wool, a bristle
brush or metal polishes. Only Mopar cleaners are
recommended. Do not use oven cleaner. Avoid auto-
matic car washes that use acidic solutions or harsh
brushes that may damage the wheels’ protective fin-
ish.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
•Use Mopartouch up paint on scratches as soon as
possible. Your dealer has touch up paint to match the
color of your vehicle.
Interior Care
Use MoparFabric Cleaner to clean fabric upholstery
and carpeting.
Use MoparVinyl Cleaner to clean vinyl upholstery and
trim.
MoparTotal Clean is specifically recommended for
leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth

2. Use specified fuses only.
3. Always properly reinstall the cover.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Fuse and Relay Center, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
•The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
•As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
