ok i know this is a shot in the dark and very hard for anyone to diagnose without hearing or seeing the vehicle.but who knows,maybe one of you guys have run into this exact issue.the noise is very regular,happens everytime,exact same time.whenever you start the car and put in gear(which it does pretty smooth)within about 10 feet of pulling off or backing up,you get a quick scraping sound like a piece of metal rubbing the road,then it is gone and you dont hear it anymore.only when you start the car and pull off do you hear it briefly.
