This may be due to driveline tension between the axle and hub keeping them engaged. To correct the condition, shift the vehicle from DRIVE to REVERSE to release the driveline tension. This is a normal operating characteristic of the vehicle and replacement of the hublocks is not recommended. If the concern remains after shifting into REVERSE and allowing the vehicle to move approximately 5 feet (1.5 meters), remove and inspect the hublocks for any damage. Refer to Workshop Manual (WSM), Section 308-07A. Repair as necessary.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10199653-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10199653-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10199653","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2017,"year_to":2022,"match":"base","vehicle_ids":["2017_ford_f-250","2018_ford_f-250","2019_ford_f-250","2020_ford_f-250","2021_ford_f-250","2022_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2017,"year_to":2022,"match":"base","vehicle_ids":["2017_ford_f-350","2018_ford_f-350","2019_ford_f-350","2020_ford_f-350","2021_ford_f-350","2022_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2017,"year_to":2022,"match":"base","vehicle_ids":["2017_ford_f-450","2018_ford_f-450","2019_ford_f-450","2020_ford_f-450","2021_ford_f-450","2022_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2017,"year_to":2022,"match":"base","vehicle_ids":["2017_ford_f-550","2018_ford_f-550","2019_ford_f-550","2020_ford_f-550","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.
