X making a strangle metal rattling noise.. Help

[beast]

Alright, so I noticed this weird rattling noise today when I drive. The best way I can describe it is if you put a piece of metal inside a metal bucket or something and rattled it around, that's what it would sound like. The car still runs fine. The noise only occurs when I am moving, not at a stop. It also seems to come and go a little bit, but I can't really pinpoint the conditions that make it change. Any ideas?? Thanks

Heat shield on the muffler or cat.

If it is a cat or exhaust shield, the sound will probably change depending on the rpm of the engine. Its common for the cat heat shield to come loose. Easy fix, wrap a large hose clamp around the whole thing.

It got worse and the left rear wheel started grinding, so I figured it wasn't the heat shield and took it in. The brake adjuster spring thingy broke off, and was rattling around inside the drum. Fixed, and luckily it didn't damage any other parts in the process.
