4-Wheel Drive - 4X4
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
In 4X4, the range sleeve remains in the same position as it was in 2WD. The action of the shift lever causes the mode sleeve to move rearward, locking the drive sprocket and chain to the rear output shaft. This causes both the front and rear wheels to be driven in the high range.
