Ford Motor Company (Ford) is recalling certain 2023 Super Duty F250 and F350 vehicles equipped with single rear wheels and a 10.5-inch rear axle shaft. The left rear axle shaft may have been improperly heat-treated during manufacturing and may break.
A broken rear axle shaft can result in a loss of drive power or vehicle rollaway when the vehicle is placed in park. Either of these scenarios can increase the risk of a crash.
Dealers will inspect the left rear axle shaft date code and replace the axle shaft as necessary, free of charge. Owner notification letters were mailed October 17, 2023. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 23S49.
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.
