I don't get it either. The fork plate (the silver-ish part in the center of the left photo, if I'm not using the right term) rotates freely when I loosen the boss stud. I'd actually never realized that it was supposed to be bonded to the fork. Once I started having problems and taking a look at it, I assumed that the "tightness" of the boss stud held it in place. If that's not the case...do I need a new fork?
