Make sure you oil the half-ball and socket in the nose shackle. And do all the contact points in the nose mechanism while you're at it.

I thought for the longest time that my springs were making noise (because that's where it seemed the sound was coming from.) A call to Bill at Walllingford Bicycle Parts, and he told me about the secret half-ball and socket. I had no idea that's what was inside the nose shackle. (Just in front of the adjustment nut)

Oiled that up with Boeshield and the noise was gone.
