It is coming from the front end, and is very loud when you turn in either direction. It almost sounds like something big has broken off and just flopping around.

This is a common problem and it sounds like one of the wheel bearing hubs is not working right. I would replace the both if you find one to be bad. Here is a diagrams to help you see how the system works below.

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
