The remedy
Ford will notify owners, and Ford or Lincoln dealers will inspect the rear axle differential fluid level and adjust it, or replace the rear axle as necessary, free of charge. The recall is began May 22, 2020. Owners may contact Ford customer service at 1-866-436-7332 or TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000188.
