FORD 2005 F-550 v.2 - Manual (Page 177)

• Disconnect the trailer tow electrical connector to prevent blown fuses
caused by water entering into your trailer’s electrical wiring.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants any time the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.
RECREATIONAL TOWING
This applies to all 4x2 trucks with rear wheel drive capability.
An example of recreational towing is towing your vehicle behind a
motorhome. The following recreational towing guidelines are designed to
ensure that your transmission is not damaged.
• Place the transmission in N (Neutral).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is 50 miles (80 km).
If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must
be exceeded, you must disconnect the driveshaft. Ford recommends the
driveshaft be removed/installed only by a qualified technician. See your
local dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
4x4 with manual shift transfer case:
• Place the transfer case in N (Neutral).
• Front hub locks are in the FREE position.
4x4 electronic shift transfer case vehicles with automatic
transmissions:
Regarding recreational towing or having your vehicle towed, 4x4 vehicles
with electronic shift on the fly cannot be towed with any wheels on the
ground unless the rear driveshaft is removed and the front hub locks are
in the FREE position (with the exception of moving it as a disabled
vehicle off the road out of traffic).
