Rotate the black center in the front wheel clockwise.
The Ford F2 50 four-wheel-drive hubs will be locked when they are turned to the right. They will be online when they are turned to the left.
The direction could be different depending on who made the hubs for Ford. If there are no arrows present, with the vehicle in four wheel drive, jack up one wheel and try both directions until the hub locks.
It is Shift on the Fly but it has manual hubs. So you can put in it 4x4 in the cab but would have to get out to engage the hubs. So what i do is when i think i am going to need the 4x4 i lock the hubs before hand. Having the hubs unlocked reduces ware on the front drive tran and betters the MPG

Remove the hub cap if equipped. Remove the snap ring holding the lock out hub (regular pliers will work). Pull old lock out hub off. It is sometimes necessary to carefully tap around the hub while pulling it. Insert replacement hub. Replace snap ring and hub cap.
I have a 2005 which does have locking hubs, but that is so you can lock your differential from slipping. If you're stuck on a hill with all 4 wheels spinning, lock the hubs and your gear ratio is far apart, your front wheels won't spin, and the front wheels will actually do the pulling. Whether yours has locking hubs depends on the year of F250. Later F250's, I believe beginning with the 1998 models, do have auto-locking / manual hubs. The later F250 hubs can be activated manually or electronically. When you electronically turn on the 4wd ("shift-on-the-fly"), you engage the transfer case, front drive shaft, and front axle shafts. Also, when you electronically turn on the 4wd you activate a vacuum solenoid, which provides a vacuum source to each of your front hubs to engage them. The front hubs only connect the front wheels to the front axle shafts and has nothing to do with the front axle differential, which is an open differential unless you have a differential other than the factory installed piece.
the hubs are bad buy new ones i had the same problem
clock wise is lock
if it does not lock in while going forward then try backing up a few feet....It is a ford...lol

jack up front end and lock in the hub, when you spin the tire by hand you should see the axle shaft spin. If it does not spin it is not locking in. if it has the auto/manual hub you can check the manual part the same but for the auto part you would need a hand held vacuum pump to test.
did you get out of your vehicle and physically lock the hubs on the front wheels? there automatic locking hubs.
