Sounds like it is resonating through the chassis. I'd rule out the end links based on that sound for now. If the sound is resonating through the chassis when the wheel is rotated, I'm voting that the top hats are where the sound is being transferred to the chassis. When you turn the wheel, it can load up the springs on the coilovers *if* the springs don't have thrust bearings. Can you get someone to physically hold the spring on the coilover while you move the steering wheel to see if there's vibration coming from the spring?
