Certain 2017-2019 Model Year Explorer Vehicles Rear Wheel Knuckle and Toe Link Replacement This program is a proactive investigation by Ford Motor Company to obtain field parts for testing. Ford is voluntarily conducting this program to replace both rear toe links and wheel knuckles on vehicles always registered and always residing in the Detroit (and Toronto) area. The replacement toe links and knuckles being installed contain no enhancements and are identical to the parts being removed. It is very important that parts obtained from this program be returned to Ford for this study

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.
