Suspension noise?

Worn struts can make this noise but, you need to test this first. The other culprit is worn out control arm bushings. Follow the control arm to the bushing and spray a lot of lubricant all over it and have someone apply weight repeatedly to the fender while you listen for the noise. If the squeaking goes away (temporarily) or gets a lot quieter you know you need to replace bushing instead. Otherwise, it is probably the strut.
