Some vehicles in the Model section above may exhibit an intermittent grinding/hum/rumble noise from the front wheel area while in 2WD that goes away when the vehicle is put into 4WD. These vehicles will also have no diagnostic trouble codes (DTCs) stored in the transfer case control module (TCCM). This may be due to incomplete disengagement of the integrated wheel end (IWE) actuator assemblies. To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). Additional Model Information: equipped with an ESOF transfer case (minor feature code FMLAS)","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11027125-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11027125-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11027125","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-150","year_from":2021,"year_to":2025,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150","2024_ford_f-150","2025_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
