I have a loud clicking coming from my Ram, I think it is in the front. Loud from 15-45 mph, clicks faster with higher speed before disappearing around 45 mph. I've had brake pads clatter and rattle before, but they usually go quiet when you touch the brakes. Hitting the brake pedal makes no difference here. What is it?
