This is my first post; I registered so I could post this. My problem started about a month ago and seems to be getting worse. When I'm accelerating at a low speed, usually through 1,600 RPM, I hear this high pitched rattle/vibration that sounds like it's coming from the right rear side of the vehicle. I climbed around underneath looking for anything that was loose, but couldn't find anything.
You can hear the noise here.
I accidentally saved it sans-video, but that's not the point.
If anyone has an idea of what is causing this, I would greatly appreciate input.
