Exceptions
There are several exceptions to the Normal
Schedule:
Normal vehicle axle maintenance: Rear
axles and power take-off units with
synthetic fluid and light-duty trucks
equipped with Ford-design axles are
lubricated for life; do not check or change
fluid unless a leak is suspected, service is
required or the assembly has been
submerged in water. During long periods
of trailer towing with outside temperatures
above 70°F (21°C) and at wide-open
throttle for long periods above 45 mph (72
km/h), change non-synthetic rear axle fluid
every 3000 miles (4800 kilometers) or three months, whichever comes first. This
interval can be waived if the axle is 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. See Capacities
and Specifications (page 292).
Police, Taxi and Livery vehicle axle
maintenance: Change rear axle fluid every
100000 miles (160000 kilometers). 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
F1TZ-19580-B, or equivalent. Add four
ounces (118 milliliters) of additive friction
modifier XL-3 (EST-M2C118-A), or
equivalent, for complete refill of
Traction-Lok rear axles. Change the axle
fluid anytime the axle submerges in water.
