Hey all, the quill stem on my bike is extremely difficult to move up or down and remove from the fork. I thought maybe it was seized but when I finally got the bolt loosened (though it still doesn't turn easily) I was able to wiggle out the stem after probably almost an hour of work and some chain lube. The stem would twist back and forth but moving it up and down was an extremely slow process and impossible without the wiggling. Here are some photos. Does this look normal to you? I'm new to bike mechanics and it doesn't look how I thought it would. It also doesn't slide back into the fork, though I haven't tried too hard yet. What could the problem be and what should I do next? Thanks.
