Those are most likely the ball joints. My drivers side was doing the same thing a few months ago...I took it to the ford dealer to get the 1 ball joint that I thought it was to get replaced. The mechanic ended up saying all 4 ball joints were bad enough to replace...so they did. Luckily I have an extended warranty and it cost me the huge cost of 50$ (deductible)!!!!
It creaked/squeaked when turning, and pretty much any type of movement, in the x,y, or z direction, even when you would push on it when stopped.
