How does Ford Auto 4WD work?
Ford four-wheel-drive (4WD) systems allow a vehicle’s engine to send power to all four wheels, instead of the front wheels or rear wheels only. Many 4WD vehicles can be switched back and forth between rear-wheel drive using a switch or a gear lever in the cab.

Why is my Ford truck not shifting to 4WD?
These rings are the mechanism that engage your front wheels when you put your truck into 4WD. They’re attached to the wheel spindle and are controlled with vacuum lines from the IWE Solenoid. Often times when these systems fail, they’ll make clicking noises. A common symptom of failing wheel actuators is a truck that won’t shift into 4WD. Figure 3.
What does longitudinal force do to a 4WD truck?
Longitudinal force propels a vehicle forward during acceleration and slows it down during braking. The more longitudinal force applied to the ground, the less wheel slip. In the good old days, the mechanisms that engaged the transfer case and wheel hubs on 4WD trucks were simple.

These rings are the mechanism that engage your front wheels when you put your truck into 4WD. They’re attached to the wheel spindle and are controlled with vacuum lines from the IWE Solenoid.
What’s the difference between a 4WD truck and a regular truck?
The major difference you’ll notice while in 4WD is that you won’t have as large of a turning radius due to the cv axles being locked in. Figure 1. Constant Velocity Axles power the front wheels while allowing them to turn. The cv axles are the link between the drive train to your front wheels.
