A popping noise , seems to be from behind the dash, happens only when moving .

Hi Breece, There is a TSB (technical service bulletin) for the 2009 MKS . ISSUE: Some 2008-2009 Taurus, Taurus X, Sable and 2009 MKS vehicles built on or before 6/23/2009 may exhibit a clicking, popping, rubbing, grunting, squeaking, or creaking noise coming from the wheel well area. The noise may be heard at the top of the strut rod. Typically, the noise is heard in the front outboard wheel while turning. This noise may be caused by the jounce bumper rubbing against the strut rod, or the dust boot rubbing against the strut mount cup. Let us know if we can help you in any way. Jeff AAMCO 972-429-8504
