Official summary

Some 2003-2020 Expedition/Navigator and 2006-2020 F-150 vehicles equipped with TOD transfer cases may exhibit grinding/clicking/ratcheting noise from the front wheel area. This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure steps to remove and cap the vacuum supply line.

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.
