Front end clunk????

[phatnomad]

I'm sure this has been discussed many times here, but the front end clunk on my 2005 nomad is driving me nuts. It used to do it occasionaly but now it happens on just about every bump in the road. It happens any time I brake hard enough with the front brake to make the nose dive. If I am going 50 mph or just walking it back and forth in the garage. Even if I walk it backward in the garage and hit the front brake hard enough to raise the front end it clunks. If I can get rid of the front end clunk this would be the perfect bike for me. If you frequent the delphi vulcan forum you will notice this same post. Has anyone replaced the front springs with progressive to get rid of the noise.
