PROPELLER SHAFT
At the regular lubrication interval, check the universal joints for any
evidence of wear or looseness. Should propeller shaft vibrations occur,
stop the vehicle immediately to avoid possible hazardous consequences
or damage to other components.
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.

SCHEDULED MAINTENANCE SERVICES
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information Decal. The following services are to be performed at
scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 161,000 km (100,000 miles) should be
continued as before 161,000 km (100,000 miles).
SPECIAL OPERATING CONDITIONS
If your driving habitsfrequentlyinclude one or more the following
conditions:
•Short trips oflessthan 16 km (ten miles) when outside temperatures
remain below freezing.
•Operating duringhot weatherin stop-and-go“rush hour”traffic.
•Operating in severe dust conditions.
•Extensive idling, or low speed operation such as door-to-door delivery
service.
•High speed operation with a fully loaded vehicle (maximum GVW).
•Snowplowing.
Perform the following:
•Change engine oil and oil filter every three months, 8,000 km
(5,000 miles) or 125 hours of engine service.
•If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.
•Lube the manual transmission and the rear axle every 48,279 km
(30,000 miles) or 6 months, whichever comes first.
•See the Allison, Cummins and Caterpillar Operator’s Manual.
