Hi, I get frustrated with trying to diagnose wretched front end noises. Yes, I have used "Search" and have seen how dificult it can be! My 01 SEL has recently had new motorcraft springs, struts, ball joints, end links, etc. It has again developed a subtle hollow popping noise on low speed minor bumps, sounds like quietly hand tapping a drumskin---plonky plonk plonk plonk? UGH! It is present irregardless of turning or braking. When I bounce each corner, I can hear a slight click and "groan" at the passenger side strut tower but cannot be sure if that noise isn't coming from lower down. Car drives perfectly and front end is tight, no play. Any suggestions ?
