Sounds like a ball joint to me. May be wrong but if you put a floor jack under the control arm and jacked it up and turned the wheel and didn't get a noise, maybe it's because the weight of the car is off of the joint. Same thing on mom's grand marquis, until it broke and the wheel passed her as she went into the ditch.
I CONTRIBUTED TO THE WIKI! ah... turbo. I love the turbo, the boost, the speed, the sound. and its all better when you do it yourself. cheaper too.
