OP, the noise you're hearing is likely your rear shock mounts or POSSIBLY your diff mounts. Do you hear the noises as you go over slow bumps or driveways?
diff oil can cause chattering and grinding sound when its low. ask me how I know it because my front diff was low on diff oil and it was chattering and making grinding sound at slow speed. especially after been sitting for awhile and cold.
