2006 suburban makes a slight pinging noise when shifting from park to reverse. noticed mainly when vehicle is parked on inclined driveway. Is this something to be worried about? help!

Can you isolate the noise location?

Tom,

My wife’s 06 Trailblazer does the same thing. It sounds like something tapping the heat shield when reverse engages. I havn’t been able to get under the car yet to find it but it doesnt sound like anything to worry about.
