FORD 2002 F-550 v.3 - Manual (Page 219)

An alternative for towing a 4x4 vehicle is to:
• put the transfer case in neutral. On manual 4WD systems, put the
4WD shift lever in N (Neutral); on electronic shift on the fly 4WD
systems, press the 2WD portion of the 4WD control.
• unlock the front hub locks (refer to Four wheel drive [4WD]
Operation [if equipped] in the Driving chapter).
• lift the rear wheels of the vehicle using a wheel lift or a sling belt with
T-hooks.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Ford Motor Company provides a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
