Re: front suspension noise on 06 Lucerne
I had an exact issue you are having on my 01 Caravan several years ago. We replaced everything, until finally I did a bit more research, and found the problem to be the front sway bar bushings. So, in the end, it ended up being a couple of $8.00 parts. Changed the bushings, and the noise went away. (For a few years, at least). Turns out, they don't last long, and you have to change them every 2-3 years. I'll bet it's the same issue in your car.
