Damaged axle hub splines can result in a vehicle roll away when the vehicle is in park without the parking brake applied or cause a loss of drive power. Both of these conditions can increase the risk of a crash.
Ford Motor Company (Ford) is recalling certain 2021-2023 F-150 vehicles equipped with the Trailer Tow Max Duty package and a 9.75-inch heavy duty axle with a 3/4 float axle design. The rear axle hub bolt may fatigue and break, which can result in damage to the axle hub splines.
The remedy is currently under development. Owners will be instructed to take their vehicle to a dealer for an interim repair if they experience symptoms related to rear axle bolt breakage, such as a clicking or rattling noise. Interim owner notification letters explaining the safety risk were mailed January 29, 2024. A second notice will be sent once remedy parts become available, anticipated 2nd Quarter 2024. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 23S65.
