Tried to upload video but it won't.
I developed a low frequency rattle on the passenger front floor. I can feel it up front on the lower section of the hump when I place my hand on it. When parked I hear it when I shift to drive (automatic) it mostly goes away in neutral or reverse no sound. When driving I can hear it, no change in sound with throttle.
While driving I put it in neutral and the sound persist with no audible difference. Crazy thing is while in park I hear the noise and when I apply pressure with my hand on that spot the sound goes away?
I looked up under (quickly) and don't really see anything loose or hitting the hump.
Any ideas what would cause it or were you would start?
