Auto-Locking Hubs Operation (Bronco and F-150 4x4)

Four-Wheel Drive: The vehicle must be stopped when you first shift into four-wheel drive. Place the transmission in neutral and the transfer case selector in the 4H or 4L position. The hublocks will automatically engage when the vehicle is driven. The transfer case may then be shifted between 2H and 4H with the vehicle moving, as long as the automatic hub locks remain engaged. The hubs will remain engaged until the disengage sequence is performed.

Two-Wheel Drive: Place the transfer case in the 2H position. To disengage the automatic hub locks, shift the transmission to move the vehicle in the opposite direction (forward or reverse) and drive a minimum of 10 ft. (30 m) in a straight line.

CAUTION: Never shift from 2H to 4H with the automatic hub locks disengaged while the vehicle is in motion. If it is necessary to shift to or from 4L, bring the vehicle to a full stop before doing so.
