I've been having a terrible creaking coming from the front end and also a bit of play developing. Main headset nut is sufficiently tight and bearings are good. i noticed what I think is the crown of the fork separating. I assume this top piece is metal because that's what the stem bolts to, but I don't know how it is connected to the rest of the fork. Can someone please let me know if they have an obvious separation like seen in these pics? I'm pretty concerned that I'm just one hit away from my base bar completely detaching from the fork.
