In this review the reviewer looks at the left driver side power running board motor and bracket assembly for 2015-2017 Ford Expedition and Lincoln Navigator with a 119.0 in wheelbase. The bottom line: this replacement part restores automatic pedal function most of the time and is best for owners who need a direct-fit, OEM-replacement style unit rather than a custom solution. It is presented as a practical repair option that replaces OEM numbers FL7Z-16A507-A and 7L7Z16A507C and comes with a two year warranty.

Key Features

• Compatibility: Designed specifically for 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator with a 119.0 in wheelbase, ensuring a direct replacement fit when the vehicle matches that wheelbase.
• Replacement Function: Restores the automatic pedal operation by replacing a failed hinge or motor, which are common causes of a jammed or non-moving running board.
• OEM Fit: Replaces OEM part numbers FL7Z-16A507-A and 7L7Z16A507C so installation aligns with factory mounting and connections in compatible vehicles.
• Quality Assurance: Manufactured by an ISO-certified maker and 100% factory tested to meet or exceed OEM requirements for durability and reliability.
• Warranty Support: Includes a two year warranty to provide post-installation protection and direct support if issues arise.

Who It's For

This part is aimed at owners of 2015-2017 Ford Expedition and Lincoln Navigator models that have the 119.0 in wheelbase who need a like-for-like replacement for a failed left driver side running board motor or hinge. It is a practical choice for do-it-yourselfers or independent shops that want a tested, OEM-style assembly that installs like the original.

Those who should look elsewhere include owners of the 131.0 in wheelbase models or drivers looking for upgraded aftermarket running boards with different motion profiles or finishes, since this product is a direct replacement and not a cosmetic or performance upgrade.
