It's most often needed when a U-joint failure has damaged the yoke bores or splines, or when completing a full driveline overhaul on one of these vintage drives.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issues:\u003c\/strong\u003e The single most common ordering mistake is confusing this short 8-1\/8 in. yoke with the longer 59830-series yoke used on later MR and IR drives. The part numbers look similar and both fit the U-joint assembly — but the length difference means they are not interchangeable. Always confirm with the drive serial number and the correct diagram before ordering, especially since this part is NLA and may be difficult to return or exchange if incorrect.\u003c\/p\u003e\n\n\u003c\/section\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563856724004,"sku":"39385A1","price":183.45,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/ef103b8c-72f2-4349-8ab1-507738f028fa.png?v=1789417386","url":"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-u-joint-coupling-end-yoke-39385a1","provider":"Marisol Marine Company","version":"1.0","type":"link"}
