This may result in a noise, smell, or leak noticed by the customer. Inspect the rear of the vehicle for signs of rear differential fluid venting in the right rear wheel well (oil staining in the wheel well liner and/or oil residue on the wheel end assembly below) or leaking from the rear differential. If signs of fluid leaks are found from any seals, repair as necessary. Refer to Workshop Manual (WSM), Section 205-02. If no seal leaks are found but fluid is venting, drain the rear differential and re-fill with fresh rear differential fluid. Remove the vent tube and use compressed air to verify that the fluid vent tube is clear. Reinstall the vent tube. Engineering is investigating, monitor OASIS for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10215368-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10215368-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10215368","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer"]},{"make":"FORD","model":"EXPLORER POLICE INTERCEPT","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator","2022_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
