"Boing" noise in rear area when raining/snowing
Whenever there seems to be weather (rain/snow) and I go over a speed bump or make a turn the rear of my car makes a "boing" noise. Like something is rolling around and bangs into a hollow metal structure. I have checked my trunk and nothing is loose. Also, it only seems to happen when their is rain or snow.
