Is there a locking hub on a Ford 4WD?
Locking Hubs – Yes on No? In the beginning, Ford used manual locking hubs on their 4WD vehicles. This required you to get out and physically turn a knob on the front wheel hubs to lock the wheel and the axle shaft together. Then in the late 1980’s, Ford began offering automatic locking hubs that did not require you to lock them by hand.
What happens when the PVH hub breaks on a Ford 4×4?
The PVH hub uses a plastic retainer ring with a steel circlip that secures the axle in place in relation to the hub seal. When this ring breaks, and they do, the axle will move toward the front differential, and the sealing surface on the axle will lose contact with the main vacuum seal. This is the beginning of the end.

The transfer case shift motor was quite troublesome and problematic in earlier models of the F150 life. Since 2004+ they’ve been more robust and seldom cause issues.

Why does my 4 wheel drive not engage?
Basically, The IWE requires constant vacuum pressure to keep the drivetrain in 2wd mode. Once there is a leak the pressure is lost and the hub will “dislocate” and attempt to engage 4H. If there is a leak or only partial vacuum pressure loss, the Hub won’t fully engage.
