2010 5.4L SCrew // I notice a loud 'pop' sound coming from under the front end and sometimes under the back end of the truck. I can't really tell, but it almost seems like it's coming from the center; not left or right really. It will NOT pop twice consecutively if I turn the same direction... For example: if I turn right, it'll pop. If I turn right again, it will not. But if I turn left, it will. So only when I switch directions of the last turn - if that makes sense... And it will only do it on relatively hard turns; not if I'm granny turning.

Any idea what the hell this might be? I'm thinking a loose bolt or something, but not freaking clue.
