If you find rust or water contamination in the joint area, inspect the entire input assembly before reinstalling the drive. Replacing only the universal joint while leaving compromised bearings or sealing surfaces in place often leads to a second drive removal sooner than expected.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564033736740,"sku":"3860230","price":1361.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/634c9c55-ffb5-4942-b650-308521929aa4.png?v=1789155918","url":"https:\/\/marisolmarine.com\/products\/volvo-794","provider":"Marisol Marine Company","version":"1.0","type":"link"}
