Suspension Noise problems of the 2009 Ford Focus

It first started when I was driving down the highway and I started to feel my steering wheel shake. Nothing major, I just thought it was out of alignment. Days later, I had my front windows rolled down when I was pulling out of my drive way and I could hear my front and rear suspension creaking really bad. And now even when the cars turned off and not moving at all its still making a high pitched screeching noise coming from the suspension noise. . . No clue how that's even possible. I know its not coming from the engine cause the cars turned completely off, and I've tested it out with the hood open to see if I could possibly hear it better but im still hearing it from the front and rear suspension area. I've googled "Ford Focus suspension problems" and tons of other people have had similar problems with their suspension from Focuses from 2000-2011. I did more reading and peoples camber will start to change to the point where they're buying new tires every year. . . Im just saying I don't want a front suspension part to break apart down the highway when im driving 70 and have me crash into a ditch or a truck or something like that. Definitely something to check out.
