Just today a loud repetitive popping/clanking noise began coming from the driver's wheel area. The popping gets faster with increased speed. It only does it when the car is in motion, without the gas pedal being depressed (coasting). It doesn't do it when I'm idling at a stop light, parked, or pressing the brakes or gas while in motion. The noise is definetly coming from the driver's side front wheel or the immediate area around it. I put an underdrive crank pulley on about a week ago, and checked that but there seems to be nothing wrong with it or the belts. I'm thinking it's something to do with suspension, my first thoughts are axel or cv joints maybe? Can anyone help??????
