Technical Service Bulletin TSB 25-2613 — 2021 FORD BRONCO

This article supersedes TSB 24-2408 to update the parts list. 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.
