My 2003 RWD is getting on my nerves. I hear a loud clicking sound from the LF wheel on each tire rotation. It was doing this for weeks. Today I replaced the rotors, bearings, seals and pads. It's now even louder! The calipers aren't hanging up. It only does it when the weight is on the wheels, doesn't matter if its in neutral or gear, but only going forward! And it wont do it when lifted off the ground. I didn't see any markings of any kind on the old Rotors or anything else. Sounds like a baseball card in the bike spokes, but metallic.
