Whenever I am turning right or left and going over any sort of bump I hear a loud rattling/popping noise. It sounds like something is loose, but I really have no idea. If I go slow enough I wont hear anything, and if I am going straight over the bump I hear nothing. Any and all ideas would be very helpful. Thanks.

Side note. I hear this noise coming from the rear of my car

 

May or may not help...

Could be the axle pop. It's pretty common. Do a search for a DIY.
