The official notice
Defect
Ford Motor Company (Ford) is recalling certain 2020 F-350 trucks equipped with 7.3L gas engines and ambulance prep packages. These vehicles were ordered with Wide Track rear axles, but were built with base (narrower) axles. Depending on the body installed by the body builder, the inner tires on the dual wheel rear axle may contact the body.
Safety Risk
Inner tire contact with the body could result in a tire blowout, potentially causing a loss of vehicle control, increasing the risk of crash.
Remedy
Ford will notify owners, and dealers will rebuild the rear axle as a Wide Track axle on vehicles already built. For remaining vehicles, body builders will be given the option to accept the base axle and build a different second unit body that meets Ford's specifications or have the rear axle rebuilt as a Wide Track axle, free of charge. An interim letter notifying owners of the safety risk was mailed on October 23, 2020. The recall began January 11, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S57.
