Not sure what forum to put this in so if this is wrong I apologize:
on my 2012 ram 1500 I have noise that sounds like a big washer being rattled around in a plastic cup while I hit bumps. I looked to see if anything was loose-lugs, brakes, suspension but found nothing. only wear indicators I see are what looks like the bolts for the front strut is contacting the plastic inner fender. I just cant see that making that much noise. Any ideas? It's new so taking it in is no big deal, or cost, but my time, like yours is valuable .
