Got it. I tried to remove it but no matter which way I turn the bolt, there is significant resistance. Can you tell me which way it SHOULD turn to loosen? I assume counter clockwise (the old "lefty loosie"), but it turns a bit and then gets very tight. I tried the opposite direction, and same thing - it turned a bit and then tightened. I would prefer not to make it worse, so I thought I'd ask before I charged ahead.
