FORD 2009 Expedition v.2 - Manual (Page 281)

Exceeding these limits may allow water to enter vehicle components:
• causing internal damage to the components.
• affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
Note: Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to the Climate
controls chapter for more information.
2WD vehicles: Do not tow your vehicle with any wheels on the ground,
as vehicle or transmission damage may occur. It is recommended to tow
your vehicle with all four (4) wheels off the ground such as when using a
car-hauling trailer. Otherwise, no recreational towing is permitted.
In case of a roadside emergency with a disabled vehicle, see Wrecker
towing in the Roadside Emergencies chapter.
4WD vehicles (Control Trac four-wheel drive system): Do not tow
your vehicle with any wheels on the ground, as vehicle or transmission
damage may occur. It is recommended to tow your vehicle with all four
(4) wheels off the ground such as when using a car-hauling trailer.
Otherwise, no recreational towing is permitted. See your authorized
dealer if you must flat-tow a vehicle equipped with the Control Trac
four-wheel drive system.
In case of a roadside emergency with a disabled vehicle, see Wrecker
towing in the Roadside Emergencies chapter.
