The Dana/Spicer Model 70 is an automotive axle manufactured by Dana Corp. and has been used in OEM heavy duty applications by Chevrolet, Dodge, and Ford. It can be identified by its straight axle tubes, 10 bolt asymmetrical cover, and a "70" cast in to the housing and is visually similar to the Dana 60. The majority of the Dana 70s are rear axles, however Dana 70 front axles do exist. Both front and rear axle variations were first offered in 1957. The Dana 70 is generally regarded to have more strength than a Dana 60 but not as much as a Dana 80. Gross axle weight ratings are often lowered by the vehicle manufacturer for safety and tire reasons. == General specifications == * Ring gear measures 10.5". * 3.5" diameter axle tube. * Inner axle shaft spline counts are 23, 32, and 35 * Pinion shaft diameter: 1.75" * Pinion shaft splines: 10 and 29 * Gear ratios: 3.07:1 - 7.17:1 * Axle Shaft diameter * *1.41” Front (35 Spline) * *1.50” Rear (35 Spline) * Axle spline diameter * *1.50” Front (35 Spline) * *1.50” Rear (35 Spline) * 1480 Universal Joint (Front axle) * All basically the same in the cheaper Dana 60 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dana 70」の詳細全文を読む スポンサード リンク
