Hey guys,
Let me describe this and see what you guys think. I occasionally hear an odd hollow thumping sound but I can't find where it's coming from. Its driving me nuts.

Let's say I'm driving down Brookwood Parkway in Hillsboro. Its speed limit varies, but it seems rather consistent at 35mph. If I come up to the stop light intersection and the light goes from red to gree, I naturally slow down for the red and then I typically hear the thump as I let off the break and transition to throttle.

My battery is secured and that was the first thing I thought. Any other ideas?
