What It Helps Address

• 4WD hubs that do not lock or unlock correctly
• Intermittent front axle engagement
• Faults related to hub locking solenoid control
• Loss of proper 4WD transfer of power at the front hubs
• Electrical issues at the solenoid connection point

Installation Notes and Tips

Confirm the terminal style, 2-terminal layout, and housing shape before installation. Some earlier Ford and Lincoln applications require a 13 mm width and a node at the 6:00 position, so match those details to the original part. This unit does not include a wiring harness, so reuse the existing harness if it is in serviceable condition.

Quality Assurance

Dorman replacement components are built to match the original equipment application for direct-fit service on the listed Ford and Lincoln vehicles. Verify fitment by year, make, model, and connector details before ordering.
