Official summary
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.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
