This bulletin applies to 2008-2016 Chrysler Town & Country vehicles. An abnormal rattle may be heard from the spare tire heat shield near the exhaust. If the heat shield is missing, replace it. If loose, or when replacing the shield, use the upgraded threaded hex nut to secure the shield and tighten to 35 in-lbs.

This threaded nut replaces the original self-tapping stamped-steel nut. Note that if the shield is missing, carefully inspect the spare tire for heat-stress damage.

Example of the original self-tapping nut.
