What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 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.

Read by machine from the document NHTSA serves (1 page), read Oct 28, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 55275 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 55275 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 55275 cover?
The manufacturer filed it against 4 model years: 2024 Ford F-250 Super Duty, 2024 Ford F-350 Super Duty, 2024 Ford F-450 Super Duty, 2024 Ford F-550 SD. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
