Sorry...no audio file available, hopefully this will make sense: Whenever I step on it hard, I hear a "clunk clunk clunk..." noise towards the rear axle. It sounds like it somewhat tied/related to a moving part based on the noise pattern as it the "clunks" are getting faster and faster as the car accelerates. It doesn't happen at the very start, but it in 40mph and above range. As soon as I get off the juice, the noise stops instantly. Any idea? Based on how it sounds, I was thinking it may be traction-control related, but it seems a bit loud and it also is not audible from 0-40ish, so that doesn't seem right either. Slip start disabled and dry pavement. This is a P90DL It happens in both Sport and L mode. I am planning on swinging by a SC soon, but wanted to run this by this always knowledgeable crowd first.
