I am having a sound that's like pulling an empty can down the street. It appears to happen on D and not R. It is loud when speeds are slow, but not noticeable when it is fast. I am thinking it is the CV joint, can someone verify this?

 

I have has something similar.....my car has been making like a rattling sound forever, however it comes from the back...it sounds like my spoiler is loose and that it rattles against my trunk......i hear it all the time, when going over bumpy road. or even when just driving at low speeds.....Where is ur noise coming from?

 

Seem like the front wheels, and it is very loud.
