2008 Spectra SX front end noise

My daughter's 2008 Spectra SX has a rattle noise in the front end. It seems to come from both side, and every little bump in the road will produce it. I replaced the sway bar link pins, as they were worn, but the noise is still the same. The struts seem to be OK, they function well. It just seems like something is loose upfront, but I can't find what it is....Any Ideas???
