4x4 Auto Mode
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
Torque from the transmission is transferred to the input shaft which drives the rear output shaft that drives the rear axle assembly. The electromechanical clutch assembly drives the drive sprocket after the 4x4 electronic module activates the clutch coil. The drive sprocket turns the drive chain that rotates the front output shaft and the front driveshaft.
