The official notice
Defect
On certain pickup and chassis-cab trucks, the owner's manual and service manual list the wrong torque specification for the wheel nuts. As a result, some trucks may have had the lug nuts over-tightened during servicing. This can damage the wheel studs and, over time, they could break. If this happens, a wheel could separate from the truck. Note: This recall only affects trucks equipped with dual rear wheels and flanged lug nuts.
Safety Risk
A wheel separation could cause a loss of control and increase the risk of a crash. A wheel that separates could also hit another person or vehicle.
Remedy
FCA Canada will contact owners by mail and instruct you to take your truck to a dealer to inspect and replace the wheel studs, as necessary. They will also provide an update for the torque specification listed in the owner's manual.
