So I bought a pop up last year. Winch was a little stiff. Now after having it out on a few trips its getting even worse. Two hands and lots of effort to crank down. I have to push on the bar while turning the crank, then pull on the bar to finish the rotation. I want to replace the winch but I can't find the model #. Where is it on the winch or does anyone know off hand what it might be? Its a front passenger mount.
