inadequate maintenance and to prolong the life of the vehicle.
General Maintenance Information
NOTE: This is a generic maintenance schedule for all Ford, Lincoln and Mercury vehicles. There may
be items listed that do not apply to all vehicles.
The Normal Schedule applies to operation of the vehicle under typical, everyday driving conditions.

If the vehicle is operated in one or more of the following special operating conditions, those additional
services will be required. The special operating conditions are:
ztowing or carrying heavy loads.
z extensive idling and/or driving at low speeds for long distances.
z driving in dusty conditions.
z off- road operation.
There are also exceptions to the Normal Operating Schedule which will require more frequent
maintenance for some components. Those exceptions are:
znatural gas and propane vehicles — fuel tank intervals.
z normal vehicle axle — maintenance and lubrication.
z police and taxi vehicles — maintenance and lubrication.
z engine oil and yellow coolant — time and mileage-based interval.

Normal Vehicle Axle Maintenance
Rear axles and power take off (PTO) units containing synthetic lubricant and light duty trucks equipped
with Ford- design axles are lubricated for life. These lubricants are not to be checked or changed
unless service is required, or if a leak is suspected, or the axle assembly has been submerged in
water.
The axle and PTO should be changed anytime they have been submerged in water. Non- synthetic
rear axle lubricants should be replaced every 4,800 km (3,000 miles) or three months, whichever
occurs first, during extended trailer tow operation above 21°C (70°F) ambient and wide open throttle
for extended periods above 45 mph.
The 3,000 mile lube change interval may be waived if the axle was filled with 75W140 synthetic gear
lubricant meeting Ford specification WSL- M2C192-A, part number F1TZ-19B546- B or equivalent. Add
four ounces of additive friction modifier C8AZ-19B546- A (EST-M2C118- A) or equivalent for complete
refill of Traction- Lok rear axles.
The axle lubricant should be changed anytime an axle has been submerged in water.
Police and Taxi Vehicle Axle Maintenance
Replace rear axle lubricant every 160,000 km (100,000 miles). Rear axle lubricant change may be
waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-
M2C192- A, part number FITZ-19580-B or equivalent. Add four ounces of additive friction modifier
C8AZ- 19B546- A (EST-M2C118- A) or equivalent for complete refill of Traction- Lok rear axles.
The axle lubricant should be changed anytime an axle has been submerged in water. Klj . 10 ba
