01 Ford Taurus suspension noise. Recent work done?

HI
Today I just replaced the front Springs and struts, lower ball joints, and sway bar links. I still have a clunking noise that sounds like a hollow metal clanking noise that I can hear really well at low speeds and small bumps. Sounds like a hollow metal pipe clanking with another pipe if that helps.

What you can do is to look underneath the car. Move every part till you discover the clanging metal. Otherwise a new visit to the mechanic will cost you a pretty penny. I used to have exactly the same problem and that's what I did and worked. Good old fashion common sense.
