We are using a worm box this year as well. At first we had some real problems with the worm gear getting worn very quickly and the jamming the whole assembly. Our problem was the the center to center distance was to large. we made a new box with tighter spacing and that fixed all our problems. You also might want to make sure that the output shaft on the gearbox is not bent at all, one of ours was and as it rotated it varied the center to center distance to the point that sometimes it would be to tight and sometimes to loose.
