Why does my car make a knocking noise when I drive over bumps?

Why does my car bang when I hit a bump?

Why does my rear suspension make a knocking noise?

There are several things that could be causing the knocking sound from the rear suspension. My first guess was worn out bushings allowing metal-to-metal contact, broken sway bar end-links, or worn out shock mounts (top or bottom). If you can, pop the rear tire off and inspect the suspension mounts for cracked rubber or worn out parts.
