Over time, stub shaft splines can twist or strip, and the main hub vacuum seal will degrade—causing automated four-wheel-drive systems to fail to lock into place. Sourcing individual pieces can delay your repair, so this kit eliminates the guesswork by packaging a high-strength outer stub shaft along with the critical main inner knuckle vacuum seal, thrust washers, snap rings, and needle bearing components. Choosing genuine Spicer OEM parts ensures exact factory dimensions, direct structural integrity, and long-term fluid protection.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003e\u003cb data-path-to-node=\"8\" data-index-in-node=\"0\"\u003eKit Highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"9\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,0,0\"\u003e\u003cb data-path-to-node=\"9,0,0\" data-index-in-node=\"0\"\u003eEssential Single-Side Pair:\u003c\/b\u003e Combines one premium outer axle stub shaft along with the heavy-duty main outer axle-to-knuckle vacuum seal and matching thrust washer hardware.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,1,0\"\u003e\u003cb data-path-to-node=\"9,1,0\" data-index-in-node=\"0\"\u003eGenuine Spicer OEM Quality:\u003c\/b\u003e Forged from premium, heat-treated steel alloy and specialized elastomeric compounds to handle extreme torque spikes and resist tearing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,2,0\"\u003e\u003cb data-path-to-node=\"9,2,0\" data-index-in-node=\"0\"\u003eFixes Common Automated 4WD Issues:\u003c\/b\u003e Replaces dried or damaged factory knuckle hub seals to immediately restore the vacuum pressure required for reliable automatic Pulse Vacuum Hub (PVH) engagement.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,3,0\"\u003e\u003cb data-path-to-node=\"9,3,0\" data-index-in-node=\"0\"\u003eDirect Application Fit:\u003c\/b\u003e Engineered specifically to meet original equipment standards for leaf-sprung \u003cb data-path-to-node=\"9,3,0\" data-index-in-node=\"101\"\u003e1999–2004 Ford Super Duty\u003c\/b\u003e monobeam Dana 50 and Dana 60 front axle assemblies.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eVehicle \u0026amp; Axle Fitment:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003e\u003cb data-path-to-node=\"11,0,0\" data-index-in-node=\"0\"\u003eMake:\u003c\/b\u003e Ford\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003e\u003cb data-path-to-node=\"11,1,0\" data-index-in-node=\"0\"\u003eModels:\u003c\/b\u003e F-250 Super Duty \/ F-350 Super Duty (4WD Models)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e\u003cb data-path-to-node=\"11,2,0\" data-index-in-node=\"0\"\u003eYears:\u003c\/b\u003e 1999, 2000, 2001, 2002, 2003, 2004\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,3,0\"\u003e\u003cb data-path-to-node=\"11,3,0\" data-index-in-node=\"0\"\u003eAxle Profile:\u003c\/b\u003e Front Monobeam Dana 50 \u0026amp; Dana 60 (Leaf Spring Front Suspension)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,4,0\"\u003e\u003cb data-path-to-node=\"11,4,0\" data-index-in-node=\"0\"\u003ePosition:\u003c\/b\u003e Front Outer Axle Shaft \/ Steering Knuckle Assembly (Fits Left or Right Side - Sold Individually)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spicer","offers":[{"title":"Default Title","offer_id":43563542020170,"sku":"PLAT-SPICER-KIT197","price":177.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/5560\/6858\/files\/12_48e30d26-bd85-407d-87f0-43ed73564a5c.jpg?v=1777818543","url":"https:\/\/platinumperformanceparts.com\/products\/outer-axle-stub-spindle-shaft-seal-ford-f250-f350-super-duty-dana-50-60-1999-2004","provider":"Platinum Performance Parts","version":"1.0","type":"link"}
