Where does it sound like its coming from? Front or rear? Going in straight line or turning in either direction? 2wd or 4wd?

It definitely resonates from the center of the vehicle if you're going down hill. You can hear it clearly bouncing off the wall next to me. I thought it might be the exhaust touching a metal shield or cover plate of some kind. The noise stops once the vehicle is leveled out on flat ground.

Do you have air ride? Maybe the compressor?

I wonder if something is loose underneath and when your at an angle it causes things to touch and cause vibrations. Diagnosing this may be hard to do without parking on an angle and crawling underneath and look around to see if anything obvious is going on.

I don't have the Adaptive Air Ride, just the Magnaride. And the sound is coming from underneath the center of the vehicle, not the 4 corners. I'm at the dealership now, and showed them this video too.

It could be the heat shield vibrating against the exhaust. Or something comperable.

The chrome trim and steering wheel bowtie let sunlight glare in my eyes on my 22 tahoe. parts guy says they make trim in black but wouldnt guarantee it would fit. Anybody else have this problem?

not the same thing, but our 21 Yukon had this going on when we sold it



that should be pretty easy to diagnose once it starts doing it...especially since it does it when stationary...my only question would be if it does it in park when at that angle or does it have to be in gear?

Went to the dealership yesterday and they gave me the oil change I was suppose to get last Thursday. They also surprised me and replaced the crooked AT4 black badging on my passenger door.
