If there is no play in the steering its the sway bar rubber mount as these guys say below:

I had the same problem and it was the struts up front. The retaining nut had a little bit of play between it and the top plate. I just took the strut out tightened it down and reinstalled. Its about a 1.5 hour job for the moderately experienced.
check your stabilizer links as well as your sway bar bushings. the sway bar bushings might look ok but what happens is the hole gets egg shapped causes clunkinking noise s going over bumps. just had the same problem in my shop. 2002 dodge caravan.
