What does this mean?\u003c\/p\u003e \u003cp\u003eIn simple terms, the steering knuckles are the parts that pivot at the ends of the axle beams when you turn your steering wheel. With a closed knuckle axle, the back side of the steering knuckles are sealed to keep lubricant in and water out of the axle u-joints and knuckle bearings\/bushings. The axle u-joint totally enclosed by the steering knuckle and knuckle ball welded to the end of the axle tubes. The axle u-joint is not visible unless the axle is disassembled.\u003c\/p\u003e \u003cp\u003eWith an open knuckle axle, the axle u-joint is exposed and it is readily visible with a mere glance. Open Knuckle Axles can use either ball joints or king pins which have their own seals.\u003c\/p\u003e \u003cp\u003eUp until the mid-1960's, almost all production 4x4s through the 1 ton class had closed knuckle front axles. Ford started the trend to transition to open knuckle axles with the 1966 F100 and Bronco. At the start of the 1976 model year, all domestic 4x4s rated for 1 ton or less was built with open knuckle axles. The biggest drawback to closed knuckle axles is maneuverability. Closed knuckle axles can usually only turn 28 to 30 degrees. Open knuckle axles can often handle a 40-42 degree turn.  A vehicle with an open knuckle front axle has a dramatically smaller turning radius compared to a similar vehicle with a closed knuckle axle. Theoretically, closed knuckle axle parts bathed in lubricant should outlast open knuckle parts, but due to leakage and lack of maintenance, closed knuckle axles often have premature part failures. \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eYears popular domestic 4x4s transitioned from closed to open knuckle axles:\u003c\/strong\u003e\u003cbr\u003e1966: Ford F100, Bronco\u003cbr\u003e1969: Chevy Blazer\u003cbr\u003e1970: All other Chevy and GMC 4x4 models\u003cbr\u003e1971: IHC Scout\u003cbr\u003e1972: Dodge W100, W200\u003cbr\u003e1972: IHC 1\/2 ton and 3\/4 ton Truck (most)\u003cbr\u003e1972: Jeep CJ and Commando\u003cbr\u003e1974: Jeep Wagoneer and Truck\u003cbr\u003e1975: Dodge W300\u003cbr\u003e1976: Ford F250\u003c\/p\u003e","brand":"Identification Help","offers":[{"title":"Default Title","offer_id":41660544778317,"sku":"IDN-124","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0206\/5741\/files\/ball-joint-type-open-knuckle-front-axle-500__15746_6943__89508.1707939819.1280.1280.jpg?v=1742691091"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0206\/5741\/collections\/manuals_20and_20technical_20information__62557_76e65a29-de0b-4b79-8928-57b9497e1d3c.jpg?v=1773182337","url":"https:\/\/torqueking.com\/collections\/manuals-tech-info-71-73-wagoneer-d30-front.oembed","provider":"Torque King 4x4","version":"1.0","type":"link"}
