I have it assembled in the following order from ground up:
fork-->cartridge bearing ---> bottom cup ---> frame ---> top cup --->cartridge bearing ---> cone ---> spacers ---> locknut
I assume it was an oversight in your assembly order list but between the "fork" and "cartridge bearing" there should be a "crown race". Did you by any any chance leave it out?
