It could be the front valance squeaking. For the longest time I thought my squeak was a control arm bushing. It reminded me of a squeak you'd hear from polyurethane bushings or such. Anyways, one day while waxing the contour I noticed the front bumper cover squeaked when I shook on it, right in front of the wheel. Some plastic looking clip/post holds it on top, so I hit it with some WD40 and it's been quiet ever since. It should only take a second to see if that's one of your problems.
