The noise is most prevalent in 3rd and 4th gear when the vehicle is warm. This may be due to normal driveline noise transmitting through the driveshaft. To correct the condition, follow the Service Procedure to replace the rear axle drive pinion flange, rear pinion seal, and reprogram the powertrain control module (PCM).","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10212103-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10212103-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10212103","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2021,"year_to":2022,"match":"base","vehicle_ids":["2021_ford_f-250","2022_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2021,"year_to":2022,"match":"base","vehicle_ids":["2021_ford_f-350","2022_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2021,"year_to":2022,"match":"base","vehicle_ids":["2021_ford_f-450","2022_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2021,"year_to":2022,"match":"base","vehicle_ids":["2021_ford_f-550","2022_ford_f-550"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
