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.
Damaged axle hub splines can result in a vehicle rollaway 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.
Dealers will replace the left and right rear axle shaft assemblies, free of charge. Owner notification letters were mailed on May 9, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 23S65.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
