I just bought a used hub style Clam shelter and one of the sides pops back in way easier than the other sides. Is there a way to "tighten" it back up? Its a JM 5000. Not sure what year. Can I just tighten the nut on the inside? The guy said he was selling it due to wanting a different door style. Sounds like he tripped a few times coming out of it, as the loose side is one with a door.
