Can you drive a Ford 4 wheel truck we no back shaft?
No, you cannot drive a Ford 4-wheel truck (meaning a 4x4 truck) without a driveshaft. The driveshaft is essential for transferring power from the transmission to the rear axle, enabling the rear wheels to receive power and turn. Without it, only the front wheels would work (if it's a 4x4 system that allows for front-wheel drive only), and the truck would be undriveable in most circumstances.
