Service bulletin 19B27-S1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 544482026-01-06. Service bulletin. Some 2017-2026 F-Super Duty vehicles may exhibit a pull/drift condition during braking. This may be due to the brake pads needing to be broken in. Repeated, heavy brake applications may assist to resolve the pull/drift condition. The Workshop Manual, Section 206-00 Symptom Chart for vehicle pulls or drifts during braking has been updated to reflect this information.
SSM 521882024-01-24. Service bulletin. 2024 F-Super Duty vehicles are equipped with XL-22 (WSS-M2C184-A1) high temperature power steering fluid that looks like clear hydraulic fluid. This fluid is an improvement in high temperature and thermal oxidative stability compared to Mercon LV. This power steering fluid is also compatible and highly recommended to use when filling or topping off power steering systems of all 2012-2023 F-Super Duty vehicles originally equipped with Mercon LV.
SSM 512612023-01-06. Service bulletin. Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00.
SSM 511202022-10-11. Service bulletin. Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00.

SSM 511042022-10-03. Service bulletin. Some 2017-2019 F-Super Duty vehicles equipped with adaptive steering may require steering wheel replacement for various reasons. The steering wheel assembly contains the steering effort control module (SECM) and steering angle sensor module (SASM). Previous software versions of the Integrated Diagnostic Software (IDS) scan tool may not have programed the SECM properly after replacement. Engineering has corrected the concern and SECM programming can now be successfully performed on these vehicles using the latest software level of IDS.
