I need help finding out a sound that comes from the steering.

There is a rubbing/grinding sound that comes from somewhere in my steering/suspension. It's driving me nuts. I just lowered my car with coilovers, and I did some readjusting and then all the sudden I start hearing this sound, only when I turn the wheel. I got my car aligned and that didn't help any. It keeps getting worse. I check the cv boot and it looks as good as new. I really don't know what it is and I need help. if anybody has a suggestion, please tell me about it! Thanks - lindsey
