Over speed bumps...sounds like struts or sway bar bushings ?.car only has 15,000 miles ....I bought extended warranty....anybody else deal with this..
Sounds like there was a TSB issued..?

 

There were many that had your problem and it was lower control arm bushings. Check and see if you have shields close to the bushings which was one of Fords fixes as the heat from the cats caused some of the problems. I also think they made some changes on later lower arms as part numbers where changed several times.

 

Those types of squeaks are hard to diagnose. I had one in the rear that took forever to figure out. I ended up using it as as excuse to upgrade the sway bars, bushings, and end links. Like dusman said, many had issues with the front lower control arms squeaking. It is a logical place to start. Good luck finding it.
