Noise in Front Suspension

The car is my 69 Dart that I just got together and on the road. About 800 miles on it. From day one its had a noise in the right front suspension. Sounds kinda like a loose ball joint. All parts are new, everything. Poly bushings upper and lower, Moog ball joints, tie rod ends, pitman and idler arm. I am using the Firm feel UCAs, LCAs, Struts, and steering box. I've pulled this thing apart, today makes the 4th time and can't find the noise. Everything appears to be tight. Nothing loose, aligned great, goes down the road straight as an arrow but hit a small crack in the pavement or a place where the upper and lower paving has seperated and it will knock just like a ball joint.

Has anyone else had a similiar problem? Any ideas?

Thanks,

Larry
