There is this noise that I have been having for awhile and its sound like its coming from my trunk. Every time I brake from a slow position such as in reverse (louder) or coming to a stop there is this loud thud. Originally I thought it was my sway bar links bushings and struts. Since I have change both my rear sway bar links and struts/mounts, I have no idea what this loud thud especially when braking in reverse can be. Anyone know what it could be?
