Sorry to hear about the vibration concern you're experiencing with your Cobalt. What is your plan of action in getting this taken care of? If I can be of any assistance, please let me know.

Probably your worn out tires then, I'd say get a nice set of tires and have them balanced well, should solve your problem.
Quick way to check your hubs:
With the car off the ground, put your hand around the back of the wheel on the knuckle/hub, and spin the wheel by hand. If the bearings are getting bad, you will feel it vibrating, get a rough feeling almost. A good bearing that is smooth you won't feel anything. If you aren't sure if you feel something, then it isn't bad
If you have bad tires/alignment/wheel balance issues, you need to fix that before it does mess up something else.
Also check your control arm bushings while you have the front end up (pry against the rear of the LCA and see if it deflects easily), it should move but not be sloppy.

It's spelled vibration. Try pronouncing viberation by each syllable and tell me if that sounds right.
When I had a vibration on my old car, it was just the tires were really bald. When I got new tires, the vibration went away.
