If it's not the sway bar end links, my guess is that you probably have worn out lower control arms: that's what the noise turned out to be on my car. Have you tried picking the front wheels off the ground yet? Jack up the front of the car and see if you get any movement from the front wheels. If so, something is definitely worn out somewhere and you should be able to look underneath and see what's moving.
