I've got a squeaky wheel too. However, it only squeaks when I'm riding it and seems to be worse when more weight is over the fork. I have disc brakes and it is not the brakes as if I apply the brakes lightly and continue to ride, I still get the squeek. I also do not believe that it is a quick release issue, as I have tried rolling with my foot applying pressure to the QR and the squeek is unaffected.

Can this be fixed by disassembling and re-assembling the hub. This squeek is about to drive me crazy!
