Hi, I have a 2007 Cobalt. Since last year it made a noise coming from what sounds like the tires. When driving on the highway I would hear it with the radio off. I was told it was tire noise. However, now I hear and feel it. It's more like a rhythmic thumping maybe? I am uploading a clip of the noise.

It is noticeable the most when driving fast and the not touching the break or the gas pedal. Also, my wheel is starting to sound like it needs power steering fluid. Like that "eek" noise.

I'm not sure if this is related but ever since I got the car, every
time I go over a pot holes, it sounds link tin foil scrunching up.

The car runs great. It gave me no issues until now. I am bringing the car into Pepboys when I get paid on Friday. I'm just worried about how much money to have prepared.

Can anyone listen to this and let me know what this sounds like it could be? Any help would be great! Thanks in advance!

Here's video of the noise I recorded: https://youtu.be/XB7h-8Pu3lg

The thumping noise can be tires or a wheel bearing drive in a circle of opposite side and see if it increases it will spin faster on opposite side so would be more noticeable. The aluminum sound may be the catalytic converter shield has broken loose from rivets and is flapping causing that so check under car.
