Hey guys. I'm needing some help. I've noticed a clicking sound in my liberty whenever I turn the steering wheel all the way left or right and hit the gas. But it only makes the noise when the air conditioner is on. I've noticed it only in reverse. So is this an ac issue. Power steering. Or transmission?
