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.
F-450 and F-550 axle maintenance:
Change rear axle fluid every 100000 miles
(160000 kilometers) under normal driving
conditions on all commercial applications.
When operating your vehicle at or near
maximum Gross Vehicle Weights, change
the rear axle fluid every 50000 miles
(80000 kilometers). In addition, follow
this 50000-mile (80000 kilometer)
schedule when operating your vehicle
under the special operating conditions,
where noted.

Diesel Particulate Filter: The filter may
need to be removed for ash cleaning at
approximately 120000 miles (192000
kilometers) or greater (actual mileage can
vary greatly depending upon engine and
vehicle operating conditions) and replaced
with a new or remanufactured (ash
cleaned) part. The filter may need to be
replaced at approximately 250000 miles
(400000 kilometers) depending upon engine and vehicle operating conditions.
In both cases, the engine control system
sets a service light (wrench icon) to inform
you to bring your vehicle to the dealer for
service. If there are any issues with the
oxidation catalyst or particulate filter
system, a service light (wrench or engine
icon) sets by the engine control system to
inform you to bring your vehicle into a
dealer for service.
