Yeah, I think I'm getting the same noise as you all. Especially under a hard right turn and REALLY jumping on it I get a .......ratcheting noise is the best way I can describe it. I can't localize the sound though. Only happens for a second or two then disappears. Temps seem to have to be cold to do it. I also got this same sound when I turned into my street. There's a slight hump at the entrance and the suspension loads up if you hit it at slow speed but full on the throttle. I can induice this sound when I hit the hump thus loading up the suspension/drivetrain momentarily which leads me to believe it's possibly the clutchpacks somewhere slipping. Center diff, rear....? Before anyone says it, I'm not pulling some Dukes of Hazard stupid slam the car into speed bumps; I'm talking a mild subtle rise in the road.
