My luck: A friend travelling to the USA is going tp pick up a new winch for me. Having inspected the winch more closely I see that the plastic housing is also damaged so it is practically beyond repair.
I must say, however, that this winch mechanism is plainly not good design. Not only does it get damaged when rolled up without the spare wheel as I unfortunately experienced. It is very difficult to operate under various circumstances. Take for example if you are travelling under harsh winter conditions on an uneven road with luggage and passengers with no help around and you get a flat tire. To get at the mechanish, you have to fold the back seat forward to get the lever, you have to empty the trunk to get at the winch from the inside and the bonus is that you have to crawl under the car to get the spare wheel. This is all workable on firm level ground under the most favourable sunny California conditions but turns into an ordeal in bad arctic weather.
I am perfectly happy with the car but I challenge Jeep engineers to try to come up with a more common sense solution for the spare tire
