Official summary
Some 2020 Expedition/Navigator vehicles built on or after 19-Oct-2020 and equipped with four-wheel drive will keep the integrated wheel end (IWE) hubs engaged under all operating conditions. Although the IWE vacuum solenoid is still present, these vehicles may not be equipped with an electrical connector for the IWE vacuum solenoid. This is a characteristic of the vehicle. Do not attempt any repairs for this condition.
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.
