Get your 4-wheel drive engaging again with the Dorman - OE Solutions 4WD Actuator 600-305 (also written 600305), an independent wheel-end actuator kit that drops in as a direct-fit replacement for the 2003-2015 Ford Expedition, 2004-2015 Ford F-150, 2004-2015 Ford Lobo, 2006-2008 and 2010-2014 Lincoln Mark LT, and 2003-2015 Lincoln Navigator. On these Ford and Lincoln SUVs and trucks, the 4WD system can become inoperable when the original locking-hub actuator fails to engage the inner axle shaft — a malfunction typically caused by the hub diaphragm material wearing out from fatigue and ozone degradation. See the Buyer's Guide tab for engine-level fitment.

  • Upgraded repair: features upgraded diaphragm material more resistant to wear and environmental contaminants than the factory diaphragm, plus a new vacuum solenoid for precise 4WD engagement.
  • Complete kit: supplies both the actuator and a new solenoid, designed to provide a more permanent repair on the specified Ford and Lincoln vehicles.
  • Restores function: if a failed factory actuator or solenoid is the cause, this kit is designed to help restore proper actuator vacuum performance and 4WD locking-hub operation.
  • Trustworthy quality: backed by a team of product experts in the United States and more than a century of automotive experience.

Frequently Asked Questions

What does this 4WD actuator kit do?

It engages the 4-wheel drive locking hub to the inner axle shaft using vacuum. The kit includes the actuator and a new vacuum solenoid for precise 4WD engagement when conditions demand.

Will it fit my vehicle?

It's a direct-fit replacement for 2003-2015 Ford Expedition, 2004-2015 F-150 and Lobo, 2006-2008 and 2010-2014 Lincoln Mark LT, and 2003-2015 Navigator. Check the Buyer's Guide tab to confirm your engine.

How is this different from the factory actuator?

It uses an upgraded diaphragm material that resists wear and environmental contaminants better than the original, and it ships with a new vacuum solenoid, designed for a more permanent repair.

What are signs the original actuator may have failed?

A 4WD system that won't engage the front axle is a common sign, often traced to the hub diaphragm wearing out from fatigue and ozone degradation. Diagnose the cause before replacing.

What interchange numbers does this replace?

It cross-references 7L1Z3C247A, 4319, and 04267. Matching one of these numbers helps confirm this is the correct actuator kit for your application.
