Ford Escape CV Boot info please!

I went to lunch today and heard a sort of metal rubbing noise each time I turned my steering wheel to the left in the parking garage. I rolled the window down to make sure it *was me*, and it was ( I came back to work and described the noise to one of the guys I work with and he said it sounded like my CV Boots may be cracked or broken. There was no noise yesterday, so i am HOPING my CV Joints will be fine! Can anyone here tell me about what I should expect to pay for CV boot repairs on a 2002 Ford Escape? Also if they tell me my joints need replaced and axle taken out etc.....is this true? I soooooo hope this isn't expensive. What kind of plae should I take it to. The Ford Dealership?? It's never a good time for car troubles...you know? Thanks for any advice or tips you can give me. I'd never heard of a CV boot or jopint until about an hour ago...so any advice will help!

I read much of the thread above about CV boots, and noticed many people describing the noise as clicking. I definately do not hear clicking. It more of a mild squeak, metal rubbing sound, only when I turn the steering wheel to the left. No noise when I turn it to the right and no noise when I brake. Maybe it's not my CV Boots - since I don't have clicking??

Thanks!
