When jacked up you can look for visual signs of wear. Another thing to do is this... Jack it up and get wheel off, do the usual safety stuff like jack stands not just jack holding the car, and chalk the tires so she's not going anywhere. You need a long 2x4, 6' plus if possible. Place one end under the control arm as close to the rotor as you can get it, I'm balzy and would just go under the rotor...lol You lift the 2x4 taking the control arm and strut assembly through as much of the range as you can muster. Put the 2x4 on end, face to suspension you can break it pretty easy. You should hear your noise this way and be able to pin point its location
