I have a 2006 300C hemi AWD with 18,000 miles. I have found a few posts on the AWD Dodge Magnums having a low speed shudder or growl in the front end when turning hard left or right. My dealer thinks I am imagining it. (I have been an auto mechanic for 25 years and I'm absolutely not imagining it). Has anyone else had this problem? There is supposedly a Technical Service Bulletin on this but the dealer can't find anything on it. Any help?
