Only problem there is that most 1/2 ton trucks haven't had locking front hubs in over 20 years in some cases. Chevy quit in 1988, Dodge in 1998, and Ford in 1997, if I'm not mistaken.
Read my post, I said "if" you have them. My F250 has them and lots of folks switch them out aftermarket.
Better check your hubs, unless you have an old square body Ford. Super duties locking hubs also lock automatically when shifted in to 4h or 4lo. Unless the vacuum actuator is broke or have a vacuum leak. Not sure why ford chose this redundant system other than the auto lock system isn't totally reliable.
Either way, you can't get 2lo out of a newer ford without modifying it.
On the flip side, there has been some good (obvious) info for the extremely misguided op in this thread, and also a greater than average amount of mis information. Be ware.
Oh and you can drive most all newer part time 4x4 trucks in 4 high on dry pavement without the driveline binding up. Turning sharp is obviously difficult though. Still not reccomended.
