- Description:
This is a Ford screw listed under base number W710279 (catalog base HS1) and finish code S439, used to fasten the four-wheel-drive integrated wheel-end or automatic locking hub actuator. Dealer catalogs name it as a screw or an actuator screw. Representative applications include F-150, F-350 Super Duty, and F-550 Super Duty along with Lincoln Mark LT and Navigator in front left and right positions with four-wheel drive; these are examples rather than a complete fitment list. The screw secures the hub actuator so it stays mounted and engages and disengages the front axle reliably. A loose or missing actuator screw can let the actuator shift, which may cause intermittent four-wheel-drive engagement, noise from the wheel end, or a stored fault. Because the thread is matched to the actuator housing and the head accepts a specific driver, using the correct screw keeps the unit seated. Confirm this screw against your VIN or a Ford parts diagram before ordering so the hub actuator is fastened as designed. This is a multi-year service part that fits across the model years of the listed Ford applications.
- Notes: Part cannot be reused/reinstalled.
