CAR TROUBLE

First off you need to fix the leak. If it's power steering fluid that could be your noise. We are not going to be able to tell you what to replace based on the info you provided. It's best if you swing by a local shop to have them take a look. Sometimes you can save a lot of money by paying for a proper diagnosis rather than guessing at what parts to change.
