The meshing noise created by the diff gears travels directly through the chassis and into the truck. The trunk is acting like a bass box and amplifying the noise. This could be attributed to the fact that yes, I have subframe bushings installed, therefor the noise travels from diff -> chassis -> bushings -> trunk.
