I am trying to remove the lower trim to replace my windshield but can't figure out how to remove the knurled drive. Help would be greatly appreciated.

I appreciate the response. The tool that you referenced is used to remove the arm. I already removed the arms. I'm trying to remove the knurled drive that the arm slides onto.
