The rattle is at the right front somewhere. Every time the right wheel goes over a bump like a manhole cover, the rattle lets itself be known. It's gotta be something fairly lightweight because it rattles very easy. I took off the front splash guard, went for a test drive; took off the right front fender liner, went for a test drive; neither one of those parts were the culprit, but at least I have those two possibilities eliminated. I've been under the car grabbing everything I can to check for tightness, but everything is tight. I should also mention that this rattle has survived numerous suspension parts replacements and motor mount replacements, but the rattle still persists to torment me. Car is a '00 Buick LeSabre and I'm throwing this thread out there in case anybody has some ideas.
