SERVICING AND MAINTENANCE
Drain And Refill

Lubricant Selection
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.
Limited-Slip Differentials DO REQUIRE limited slip oil
additive (friction modifiers).
NOTE:
Slight noise and mild shuddering may be evident while
turning a vehicle with limited slip differential on concrete
or dry pavement. These conditions should be considered
normal operation of the limited slip differential.

ARRANTY
All vehicles built over 10,000 lb (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.
Required Maintenance For Noise Control
Systems
The following maintenance services must be performed
every six months or 7,500 miles (12,000 km) whichever
comes first, to ensure proper operation of the noise
control systems. In addition, inspection and service should
be performed anytime a malfunction is observed or
suspected. Proper maintenance of the entire vehicle will
help the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts
should be tight and in good condition. Damaged
components, burned or blown out mufflers, burned or
rusted out exhaust pipes should be replaced according to
the procedures and specifications outlined in the
appropriate service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and that the cover is tight. Check all hoses leading to the
air cleaner for tightness. The air filter element must also
be clean and serviced according to the instructions
outlined in the Scheduled Maintenance section of this
manual.
