My son's 2007 accord with 189k started making an intermittent scraping sound last night. It sounds like a heat shield scraping against some moving part, but I have looked hard and don't see it. I jacked up each rear wheel and spun it and can't duplicate it. But I let it down off the jack and when the car creeps fwd or reverse you get this sound.
Can anybody help identify this from this video?
THANKS~

 

I can't tell where it is coming from, but it sounds like a rock stuck between the brake rotor and dust shield. Or the dust shield rubbing against the rotor.

Pull off the offending tire and look behind the rotor. You may have to remove the caliper and pull the rotor to find it.

 

That's definitely the sound of the dust cover and something
