Exceptions
Axle and Transfer Case Maintenance
Axle(s) and transfer case, 4X4 only, fluid
changes or level checks are not required
unless a leak is suspected or the assembly
has been submerged in water. During long
periods of trailer towing with outside
temperatures above 70°F (21°C) or at
wide-open throttle for long periods above
45 mph (72 km/h)
, change the rear axle
fluid every 30,000 mi (48,000 km) if the
rear axle is filled with non-synthetic fluid.
This interval can be waived and the
150,000 mi (240,000 km) service interval
can continue if the rear axle is filled with
75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number
XY-75W140-QL, 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 441).
Additional Axle Maintenance for Dual
Rear Wheels
Change the rear axle fluid every
250,000 mi (400,000 km)
under normal
driving conditions on all commercial
applications. When you operate your
vehicle at or near maximum gross vehicle
weights, change the rear axle fluid every
60,000 mi (96,000 km)
. In addition,
follow this 60,000 mi (96,000 km)
schedule when you operate your vehicle
under the special operating conditions
where noted. California Fuel Filter Replacement
If you register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your 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.
Hot Climate Oil Change Intervals
Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 3,000 mi (5,000 km).
If the available API SM or SN oils are not
available, then the oil change interval is
2,000 mi (3,000 km)
.
Engine Air Filter and Cabin Air Filter
Replacement
The life of the engine air filter and cabin air
filter is dependent on exposure to dusty
and dirty conditions. Vehicles operated in
these conditions require frequent
inspection and replacement of the engine
air filter and cabin air filter.
Diesel Particulate Filter
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be replaced
with a new or remanufactured part at
approximately 250,000 mi (400,000 km).
Actual mileage varies depending on engine
and vehicle operating conditions.
