runnin,
My 03 Ex does the same thing. I bet it is the track bar bushings. The ball joints were replaced when I bought it because I heard it on the test drive. It still does it, sound like it is right down front..... If you replace the bushings it should go away. If you do a search on front end clunk, or front end noise you will see several threads on this. If I remember correctly, one member replaced almost everything in the front end, except those bushings trying to chase down the noise.... He posted on here what it was doing, and the repairs he had made, someone told him to replace those bushing and the noise was gone......
