It could be your in-tank fuel pump on it's way out. Try and listen close and see if it's coming from that area (center of the hump in the rear). That's about the only thing I can think of that's moving in the back at a stop.

Could it be a hatch motor?

My guess would be fuel pump, but sometimes the hatch motor gets stuck on and will run forever. The previous owner of my car took the motor out and made it completely manual because the motor would run even after killing the ignition and it would drain his battery.

About 2 weeks before my fuel pump went out I kept hearing a whine coming from the hatch. It was actually more like a humming noise. Your sure its not coming from the differential? Or somewhere else?

A noisy fuel pump isn't necessarily a bad one. A test of pressure and flow will reveal a lot more. I had a noisy pump on one TBI vehicle for over four years, but it flowed well and made pressure. I waited for it to quit, but it never did. It's possible that the tank has shifted and the noise is now being amplified by the body and floor pan instead of being isolated.

Might help to keep your fuel level above 1/4 tank also. I had one get real noisy on the bottom half of the tank....

this is good new to me then.. Mine has been loud enough to be heard over my exhaust both inside and outside of the car.. however you have to know what to listen for to hear it, its still loud. but pressure is good.
