i dont think the 4x4 knob would pull out if the truck didnt have a rear locker. a light on the dash should come on when you pull it out, and it will automatically kick off and unlock once you get over 20 mph. thought the rear locker would be sweet for racing, but then ford screwed us there by having it un lock automatically. SPE makes a kit where it will lock and stay locked. but i dont use it enough to invest in that feature. But it comes in handy when your taking off from read lights or in stop in go traffic with a heavy load behind it. As well as pulling your boat out of the water up the boat ramp, that makes it a nice feature to have and use.
