The bolts that attach the rear driveshaft to the transfer case may become loose or damaged, which can result in the separation of the driveshaft from the transfer case.
Driveshaft separation can result in a loss of drive power or unintended movement while the vehicle is parked if the parking brake is not engaged, increasing the risk of a crash.
What to do
Dealers will inspect and replace the driveshaft bolts. If any loose bolts are found, the driveshaft, attachment hardware, transfer case flange kit, and seal will also be replaced. Repairs will be performed free of charge.
Owner notification letters are expected to be mailed on January 31, 2022.
Owners may contact Ford customer service at (866) 436-7332. Ford's number for this recall is 21S54.
