Official summary
During replacement of the electronic power assist system (EPAS) steering gear assembly on 2015-2023 Mustang vehicles, removal and replacement of the inner tie rods and bellows boots is required. To assist engineering with root cause analysis of failed steering gears, include these parts in the same package when returning warranty replacement steering gears. Make sure to avoid damage to the bellows boots or inner tie rods during removal. The steering gear should also be packaged in the original box with all protective insulators in place to properly protect it during shipping.

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.
