So here's the dealio. I've been hearing this jingling sound coming from the rear of my car when accelerating. Only happens around 3k RPM's and also hear it some when I hit bumps. It's louder under harder acceleration. My exhaust makes a lot of shit vibrate in the car so that could also be making louder. Anyone else have this issue? Haven't had a chance to get up under it and look yet.
