Squeak from front wheels when turning

I drive an 06 Prius and it just started making this squeaking sound from the wheels when I steer. When I make turns you can hear the sound both ways when turning the wheel.

I took it to the dealership for the steering recall but they didn't seem to find anything.

Anyone have this trouble before? Is it just something I can lube up to make it go away or is it something more serious?

 

Just to give everyone an update, I called up the seller and he invited me over for him to take a look. He jacked up the wheels and bent the brake protector and the sound went away!

No idea what caused them to bend in the first place but the squeak's gone away.
