I've read the other posts about front end noises, but this noise is very hard to describe. I thought it might be the wheel hub, but have been advised it maybe related to my brakes. It's a rattling-knocking noise that can be heard a low speeds, and gets louder when I make a left turn. It sounds like it's coming from the right side but is hard to tell. I can't hear it when I apply the brakes, but it comes right back when I'm off the brakes at low speed. It's very annoying and doesn't sound like it will be safe to continue driving the car with it. I was experiencing, and still am, a shuttering/grinding/vibration under even moderate breaking from high speed. it's an almost grinding noise, separate fromt the rattling-knocking noise and only under these braking conditions. Slow speed braking doesn't cause the noise/shuddering. I had this noise looked at by the dealer 3 months ago but was told the brakes are at %60 and no problems. Can anybody make suggestions. 2003 LS V6, it'll go into the dealer as soon as I'm back in town, I got a rental to go out of town for work.
