My 2001 started squeek noise when I turn the wheel while stopped. I remembered this site I saved as a bookmark. I tabbed down to NOISE and there was a suggestion about lubing steering shaft u joints. (there's an upper and a lower) So this morning I tried it and no more squeeks. Other stuff on the site as well. Maybe you've seen it before.
