EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
Normal vehicle axle maintenance
❑Rear axles and power take-off (PTO) units containing synthetic fluid and light duty trucks equipped with Ford-design axles
are lubricated for life. These fluids are not to be checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle and PTO fluids should be changed anytime the axle and PTO have
been submerged in water. During extended trailer tow operation above 70°F (21°C) ambient and wide open throttle for
extended periods above 45 mph (72 km/h), non-synthetic rear axle fluids should be changed every 3,000 miles
(4,800 km) or 3 months, whichever occurs first. The 3,000 mile (4,800 km) fluid change interval may be waived if the
axle was filled with 75W140 synthetic gear fluid meeting Ford specification WSL-M2C192-A, part number F1TZ-19580-B or
equivalent. Add friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear axles (refer to
Maintenance product and specificationsin theMaintenance and Specificationschapter for details). The axle fluid should be
changed anytime an axle has been submerged in water.
Police/Taxi/Livery vehicle axle maintenance
❑Change rear axle fluid every 100,000 miles (160,000 km). Rear axle fluid change may be waived if the axle was filled
with 75W140 synthetic gear fluid meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B or equivalent. Add
four ounces (118 mL) of additive friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle fluid should be changed anytime the axle has been submerged in water.
E–450 and F–450/550 axle maintenance
❑Change rear axle fluid every 100,000 miles (160,000 km) under normal driving conditions. For vehicles operated at or
near maximum Gross Vehicle Weights, the rear axle fluid should be changed every 50,000 miles (80,000 km). In addition,
this 50,000 mile (80,000 km) schedule should be observed when the vehicles are operated under the Special Operating
Conditions.
California fuel filter replacement
❑If the vehicle is registered in California, the California Air Resources Board has determined that the failure to perform this
maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful
life. Ford Motor Company, however, urges you to have all recommended maintenance services performed at the specified
intervals and to record all vehicle service.
Class A Motorhome
❑Change brake fluid every two years
