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 a leak is
suspected, service is required or the axle assembly has been submerged
in water. The axle and PTO lubricant should be changed anytime the
axle and PTO have been submerged in water. Non-synthetic rear axle
lubricants should be replaced every 3,000 miles or 3 months, whichever
occurs first, during extended trailer tow operation above 21 Celsius (70
degrees Fahrenheit) 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-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.
F-450 and F-550 axle maintenance
Replace rear axle lubricant every 100,000 miles under normal driving
conditions on all F-450 and F-550 commercial applications. For F-450
and F-550 trucks operated at or near maximum Gross Vehicle Weights,
the rear axle lubricant should be replaced every 50,000 miles. In
addition, this 50,000 mile schedule should be observed when the vehicles
are operated under the Special Operating Conditions, where noted,
beginning on page XX.
