Hi,
Does it sound like a clunk? Have you checked sway bar pins and other steering components? If you have and everything is good, my first suspect is the strut mount. The mount is located at the top of the strut assembly and commonly make a popping or clunking sound when going over bumps.
I attached a pic and circled the part I am referring to. The strut assembly needs removed and taken apart to replace this component. Testing is difficult simply because the assembly needs loaded with the vehicle's weight and then removed quickly which makes it difficult. Ford actually put out a technical service bulletin years ago regarding this. I will attach it for you to read and see if it mirrors what you experience.
