I need some replacement parts for my yanmar steering gear box, this winter while blowing snow it got diffficult to steer and was really hard to turn, My guess is water got into the gear box and froze because I saw oil dippingout from under the steering box earlier in the earlier this past winter. IT finally broke and the wheel spinns , took apart the steering colomn and havent tore it completely out yet, but was wondering if the replacement parts are hard to find and costs. Trying to do thing myself???:confused2:
