Some 2005-2007 Mustang Coupe vehicles equipped with 4.0L or 4.6L (excludes GT 500 and convertibles) may exhibit a "loose lumber", rattle, or chuckle sound from the front end over bumps and rough roads.
Follow the Service Procedure steps to correct the condition.
The concern is caused by a body resonance and will not get worse over time nor affect function. A new strut mount has been designed to dampen the vibration.
Replace both Upper Mount Assemblies per Workshop Manual (WSM), Section 204-01.
