As long as everything feels normal, sounds like bushings to me. Sometimes they will squeak or chirp. My LTZ has a "rushing air" sound to the shocks when I go over speed bumps or something large like that. Don't hear it any other time. I'm guessing it's just the pressure release of the stock shocks. Plan on upgrading to Bilsteins at some point, but it does bug me now...
