the hubs are also known to freeze up so you cant even turn the dial to lock. guzzle has a write up to take them apart, clean, and relube them. i did this on my 03 hubs, wasnt hard to do. but, i must have either used too much or the wrong kind of grease, because when it was really cold, the hubs would not want to auto lock. they would if i had been driving first and got the hubs warmed up. do what big sig said and lock the hubs manually. then try and turn the axle shafts by hand. just reach around the wheel and grab onto the ujoints for the front axles. if they wont spin by hand, then you have a problem with the hub. if they dont spin, then you have a problem with the auto locking feature of the hub, ie: vacuum leak...
ford does make non auto hubs for these trucks. they would say say lock and free on the outside of the hub. auto locking hubs would say auto and lock.
