Well, the sound is just getting worse lately. It seems like metal to metal. I suspect it from my rear passenger side. I check my suspension and everything is tide. I suspect my rear strut mount is dying. I have Mazdaspeed adjustable strut with Eibach spring and a stock Strut Mount. The strut mount has been almost 2.5 years. Is it possible that the strut mount is dying? Any idea what might cause the sounds? Thanks guys
