Chevrolet Repair: Wabbling in front end, front end alignment, wheels and tires

Question
I have a 2006 cobalt and I have had this car in the dealership 4 times in 5 months. When I drive no matter how fast or slow I am going my front end feels like its wobbling.  They had me to put new front wheels on, a front end alignment, and new rotters and its still doing it. They said the last time to get it balanced and its still not helping it. What can i do next? Its like im wasting my money.

Answer
If you put new wheels and tires and balanced and rotors, it sounds to me like the dealer is just throwing parts at it.  Did they check the surface runout on the hub bearings?  I have only seen two of these go bad to cause a wobble like you are stating.  But it took me a month to fix the car, having replaced all the same components you said they changed.  Have you recently hit a curb, or a really big pot hole?  If so, chances are you bent the hub bearing.  I would have them do a hub surface runout, to determine if that's it.  There really is nothing else in the car that would cause a wobble like you are stating
