Towing the Vehicle with the Rear Wheels Suspended
Note: To avoid damage to the cab roof or air deflector when towing the
vehicle backward (rear wheels suspended), the air deflector must be
removed.
Whenever possible, it is preferable to tow a disabled vehicle from the
rear by raising the rear of the chassis. When towing a vehicle with the
rear of the chassis suspended, the front wheels must be locked in the
straight-ahead position.
Vehicles equipped with a manual transmission must have at least 1.0 pint
(0.5 liter) of transmission fluid drained from the case. This prevents the
transmission fluid from entering the clutch housing and saturating the
clutch discs. Make sure that the transmission fluid is replaced before the
vehicle is returned to service.
Towing Vehicles Equipped with a Driver-controlled Differential
Lock
Note: If the vehicle must be towed to a service facility with the drive
axle wheels on the ground, it is necessary to remove the axle shafts
before the vehicle is towed.
