But everyone says They never heard this before and might need to keep replacing parts to fix it. I dont think it is the brakes as I have stepped on them and the noise is still there. I was wondering if it could be the emergency brake since I believe that is a drum in the rotor?? When it is on a lift they cant duplicate the noise..Any thoughts I would appreciate..

Can you duplicate the noise by putting your weight on the back of the car to bounce it up and down?
Is it somethiing inside the trunk? The jack and equipment under/on the little spare wheel?
It could be the shock absorber mounts. That would give a solid-sounding thud effect.
It could be the bolts holding down the line for the emergency brake on top of the arm that holds the rear wheels in place. The emergency brake just uses the piston of the caliper and mechanically pushes on it; there is no drum.
