Help guys

Alright guys. Just got new tires on my cobalt. The guys that put the tires on only had a bubble balancer. They did the best the could with balancing them. I took it for a test drive and of coarse the wheels were off balance and they were making noise. There was also a humming noise coming from the front left. I took it back to the guys and they test drove it and they thought it sounded like a dry wheel bearing. I took it to another car care place to get the tires balanced with the high speed balancer and I asked them to take it out to drive it and see what they thought. They pulled it up on their lift and they said that the wheel bearing seemed fine that they thought it was the transmission. They told me that they put it up on their lift and got the tires spinning up to 80 mph and it was still doing it. The humming sounds exactly like you put mud tires on a truck and take it down the road. I just want some advice on what I should do. I don't want to start throwing stuff on it that I don't need

If it sounds like an airplane propeller it's usually the wheel bearing. Take it to a real garage.

That's what I was thinking too. I just hope that its not the transmission. I'm going to replace the bearing here soon. It helps working at an auto parts store too but it's still damn expensive.
