Rattling or popping noise from the back

Whenever I hit a bump I have a rattling or popping noise from the back and under the driver side seat. I was told that it could be a tie rod end. I'm just wondering if it could be a tie rod end.

I was told that it could be a tie rod end or rear axle shaft bearing. Its only when I hit bumps, and usually makes the noise when the wheels fall into a pot hole or bump and come out.
