Some of the vehicles listed in the Model statement above may exhibit a loud front end clink/clunk noise that leads to the identification of a cracked or broken front differential frame mount bracket. This may be due to flexing of the front differential from driving in 4L for extended periods of time. Note: Advise the customer that 4L/Rock Crawl drive mode should only be used when necessary, as using 4L when not necessary can cause damage to the vehicle. Refer to the Owner's Manual for additional information.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11027609-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11027609-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11027609","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_bronco","2022_ford_bronco","2023_ford_bronco","2024_ford_bronco"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
