Hi,
No, it really isn't easy for it to come apart. If you only unbolted and removed the arm assembly, it sounds like you don't have them fully seated on the splines. Just to confirm, remove the wiper arms and turn on the system. See if the mounting posts are moving. My guess is they aren't fully on the splined connectors.
Let me know.
