Clunking noise when driving over bumps?

My car has a rebuilt title. It was hit on the front passenger side. It has made a clunking noise when I go over bumps and it started feeling a little loose in the steering. I replaced the front struts which tightened the steering and helped a little with the noise but it's still there. It's coming from the passenger front and is only when I hit bumps. I don't notice any noise when turning. What could it be and what do I look for to diagnose so I get the right part fixed?
