Creeking door???

Hello, my 1st post in here. I have a problem with my 2000 sunfire gt. When ever i turn my wheels more than 1/2 a turn i hear a creeking sound which comes from the passenger side. Its like a creeking or like a stretching sound. Sorry thats the best i can describe it. It sounds like its coming from the control arm (at the end) Anyone have any ideas what that is?? Some people have suggested it's the cv boots....

I would check there.
