Keep hearing this high pitched chirping sound, started I think when going over small bumps in the road, now its pretty much constant. I have 2012 Sport a/t and I have not lowered it or touched the suspension. I've been searching everywhere and haven't heard anyone else with this issue. I only have like 30,000 miles too

 

Nothing in the spare tire well? Loose jack, tools, tire, etc.

Chasing sounds in person is a PITA, over then net almost impossible. Does the sound stop when the car stops? Does it get louder the faster you go? Does it change pitch with bumps, turns? Drive next to a wall on the side the sound is on, does it seem like the sound is louder (outside the car)? Does it change when you put the brakes on?

Suggestions for diagnosing, I can't make an educated guess without more info unfortunately.

 

Sounds like dry bushings (rear springs/shocks). When I change my oil I hit the rubber spring seats and all bushings with a shot of . Chirping I heard early on (20,000 miles?) going over the small bump at the end of the driveway stopped and hasn't come back in 40,000 miles.
