small banging noise under car

Hi guys i have a 06 cobalt ss sc and when im driving slow on a rough road a banging noise starts under the car.also happens sometimes when i turn the steering wheel.maybe a problem with the steering? I have warranty from gm so if something is wrong they can fix it but just wanted to see if anyone has had this problem.thanks

Yeah I started hearing the noise around 78k I couldn't go more than a week with it making that noise before it really started to bother me! I have heard that it is common with certain chevy cars. Just before I changed mine we had to change the ones in my grandmothers HHR

I'd say either end links or control arm bushings. I was getting a clunking noise and it wasn't the end links but it was the control arm bushings

I don't think it's hitting your sway bar.... does it do it at idle?
