Summary (official text)​

Some 2024 F-Super Duty vehicles equipped with a 5th wheel prep package may experience difficulty installing a 5th wheel hitch assembly to the vehicle. This may be due to the 5th wheel hitch crossmember. If replacement of the 5th wheel hitch crossmember is necessary, use service part PC3Z-5L029-A if the Ford Accessory 5th wheel hitch prep package kit (PC3Z-5F057-A) is unavailable. The Julian Date of production is shown just below the engineering part number stamped on the underside of the crossmember. The first two digits are the year and the next 3 are the day of the year. Parts produced between 11-Feb-2024 (Julian Date: 24042) and 10-Jul-2024 (Julian Date: 24192) should not be installed and should be returned through the normal parts return process. Refer to Workshop Manual, Section 502-02 for the removal and installation procedure. 4 pieces each of fasteners W506464-S439, W719967-S439, W721524-S439, and W721840-S439 are required to replace only the 5th wheel hitch crossmember. 4 pieces of fastener W718865-S439 are required to remove the fuel tank in the procedure to raise the pickup bed.
