Chrysler (FCA US, LLC) is recalling certain 2012-2021 Ram 3500, 3500 Cab Chassis, 4500 Cab Chassis, and 5500 Cab Chassis vehicles. Incorrect information in the Service and Owner's Manuals may cause the flanged lug nuts to be over-tightened, which could result in a broken wheel stud and possible wheel separation. Wheel separation can cause a vehicle crash.
