With my limited experience, I’m going to go out on a limb and say it’s often likely due to poor maintenance. I’ve only ever had the one winch, a Toyota supplied Superwinch that I fitted early last year. Being my first winch it’s all I’ve known, so I wouldn’t know if it’s easy to pull out or not, except I’ve actually had a couple of people comment as I’ve walked it out saying they’d never seen one come out so easily. Since then, I’ve helped my brother with his Warn after he had clutch issues. It was on the car when he bought it, so we have no idea about it’s past, but it did all work at first. It took a bit of effort to spoil out though, and before he got around to checking it out, the clutch decided it wouldn’t disengage. This meant, of the three times he needed it that day, he ran it out the slow way twice, and not keen to do it a third time, sweet talked me into pulling out mine to drag him through. When he pulled it apart to see what the go was, the clutch was rusted solid, and there was a tide line on everything inside. He chose to rebuild it, new parts where needed, and though he still doesn’t reckon it’s as free as my Superwinch, it’s not far off it since the repairs. And after seeing our two winches in action, our old man chose to get a Superwinch for himself, and it free spools the same as mine.
