REAR AXLE LUBRICANT
Refer to your general maintenance information section for rear axle
lubricant level checks and lubricant change intervals.
Your rear axle may be filled with an optional synthetic lubricant which
allows the use of extended service intervals. A tag on the filler plug will
identify the use of the synthetic lubricant.
Use only a lubricant that meets manufacturer specifications (refer to
Lubricant specificationsin this chapter).
Use of a non-approved rear axle lubricant may cause internal axle
component damage.
Check your rear axle lubricant level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
3. Clean any dirt from around the rear axle filler plug.
4. Remove the filler plug and inspect the lubricant level.
5. The lubricant level should be up to the bottom of the filler plug
opening.
6. If necessary, add enough lubricant through the filler plug opening so
that the lubricant level is at the bottom of the opening.
7. Clean and install the filler plug securely.
Drain and refill your rear axle lubricant using the following procedure:
1. Drain the rear axle while the lubricant is warm.
2. Park the vehicle on level ground.
3. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
4. Clean any dirt from around the rear axle filler and drain plugs.
5. Remove the filler and drain plugs and drain the lubricant into a
suitable container. Dispose all used automotive fluids in a responsible
manner following your local authorized standards.
6. Clean and install the drain plug securely.
7. Add enough lubricant through the filler plug opening so that the
lubricant level is up to the bottom of the opening.
8. Clean and install the filler plug securely.

WHEELS
General
Wheel bearings should be inspected, lubricated and adjusted at regular
intervals. This is especially important if operating in deep sand, mud, or
water. Refer toLubricant specificationsin this chapter.
When installing wheel balance weights, they must be mounted on the
dome-side of the wheel only. Failure to do so may result in loss of wheel
weight and/or damage to brakes or wheels.
Oil lubricated front wheel bearings
During normal vehicle duty cycle, the lube and air inside the hub/wheel
cavity expands and if not vented, causes pressure build-up that could
cause accelerated seal wear.
There are two venting methods:
•a slit or small hole in the rubber check vent or
•the window
You can use either of these methods to prevent pressure build-up.
Normal maintenance
Over a period of time, if not routinely cleaned, a slight film of oil can
collect dirt around the rubber fill plug and face, which could appear to
be a leak. Routine cleaning ensures that the lube level can be easily
observed through the clear window as intended. In situations where the
window is clean on the outside but discolored on the inside, the lube
level may be checked by inserting a finger through the rubber check
vent hole.
The specified lube level for a clear window type hubcaps is from the
minimum line to + 5/16 inch above the minimum line.
If the lube level should suddenly drop dramatically below the minimum
level, see the Service Manual for diagnostic procedure.

LUBRICATION AND MAINTENANCE INTERVALS
New vehicles are lubricated at the factory. After the vehicle is placed in
operation, regular lubrication intervals, based on the type of service and
road conditions, should be established. Thorough lubrication at the
specified intervals will insure outstanding life cycle value and will reduce
overall expense.
The lubrication intervals specified should be performed at whatever
interval occurs first, whether it is months, miles (kilometers) or hours.
Only lubricants of superior quality, such as Motorcraft lubricants, should
be used. The use of inferior products will reduce the service life of the
vehicle or result in failure of its components.
Unless otherwise specified, never add lubricant unless it is the same
grade as that which is already being used. If the grade is not known or
not available, drain, flush and refill with new lubricant.
The interval between lubrication periods, oil changes, etc. depends
entirely upon operating conditions. The loads carried, speeds, road and
weather conditions all contribute to the frequency of lubrication periods.

Maintenance and specifications
211

In some types of operation, and where operating conditions are
extremely severe (such as in deep water, mud or unusually dusty
conditions), the vehicle may require lubrication after every 24 hours of
operation.
Maintenance intervals
Maintenance intervals are provided for three types of general vehicle
environments: On-Highway, City and Severe Service. In all applications,
the actual interval is determined by monitoring kilometers (miles) and
time and when the engine is due for an oil change. When the engine oil
change is required prior to the truck lubrication interval, it is
recommended that the lubrication be performed at the same time in
order to reduce your vehicle’s time out of service.
•On-Highway:60,000 miles (96,000 km) or more annually.
•City:59,000 miles (95,000 km) or less annually.
•Severe Service:20,000 miles (32,000 km) or less annually on/off
road in dirty conditions.

GENERAL MAINTENANCE INFORMATION
The Scheduled Maintenance Services listed in this section are required
because they are considered essential to the life and performance of
your vehicle.
Ford Motor Company recommends you perform the Owner Maintenance
Services listed in this section. These services are matters of day-to-day
care that are important to the proper operation of your vehicle. In
addition to the conditions described in the Owner Maintenance Checklist,
be alert for any unusual noise, vibration or other indication that your
vehicle may need service and attend to it promptly.
Use only recommended fuels, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle. Using these parts for
replacement is your assurance that Ford-Built quality stays in your
vehicle.
SCHEDULED MAINTENANCE
The maintenance or replacement of the emission control devices (or
systems) in your new Ford Motor Company vehicle (or engine) may be
performed at your expense. These services may be performed by any
automotive repair establishment or individual using automotive parts
equivalent to those with which your vehicle or engine was originally
equipped. If any parts other than Ford, Motorcraft, or Ford authorized,
remanufactured parts are used for maintenance replacements (or for the
service) of components effecting the emission control, the owner should
be assured that such parts are warranted by their manufacturer to be
equivalent to genuine Ford Motor Company Parts in performance and
durability. Please consult your warranty information booklet for complete
warranty information.
Authorized dealer maintenance
Your authorized dealer specializes in knowing all about Ford Motor
Company vehicles rather than knowing a little about all makes.
There are Ford or Ford of Canada dealer service shops ready to serve
you wherever you drive in the U.S. or Canada. They stock Ford and
Motorcraft parts, and Ford Chemicals and lubricants. You can be
confident that these meet the same exacting design and quality
standards as those used to build the vehicle originally. Dealer Service
Technicians have available training in the latest product developments
and service techniques.
