Dolly Towing (Two-Wheel Drive Vehicles)
Two–Wheel–Drive Vehicles
Two–wheel–drive, vehicles,should not be towed with
the rear wheels on the ground. Two–wheel–drive
transmissions have no provisions for internal lubrication
while being towed. To properly tow these vehicles, they
should be placed on a platform trailer with all four
wheels off the ground.
In rare cases when it's unavoidable that a two–wheel
drive vehicle is to be towed with the rear wheels on
the ground, the propeller shaft axle yoke orientation
should be marked and the propeller shaft removed
following the application service manual
removal/installation procedure.
Dust or dirt can enter the back of the transmission
through the opening created by removing the propeller
shaft if proper protection is not provided. Also, check
the transmission fluid level before driving the truck.
When the vehicle is properly attached to the tow vehicle
and is ready to be towed,turn the ignition to LOCK.
Clamp the steering wheel in a straight–ahead position
with a clamping device designed for towing.
