The nearly identical AAM 1355 U-joint in first appeared in 2003 Ram front CV driveshafts but it is already obsolescent as it provided no advantage over the original 1350 series u-joint. The published OE manufacturer dimensions for the two series of u-joints differ by only 0.003\". The difference is so small, that the manufacturing tolerances of the yokes overlap. The two series of u-joints are essentially interchangeable although changing the snap ring thickness may be required to get the best fit.\u003c\/p\u003e \u003cp\u003eA 1350  or 1355 Series U-Joint is retained in driveshaft yokes by Snap Rings that fit into grooves machined in the driveshaft yoke ears and that seat against the end of the U-Joint Cap.  For most 1972 and prior 1350 applications, the u-joints will be secured to matching end yokes by u-bolts. From 1973-1986 either u-bolts (Ford) or Straps\/Bolts (GM) are common. From 1987-on Straps and bolt are the original equipment choice for end yoke attachment. Strap and Bolts have become the preferred way to secure the u-joint caps to an end yoke. The main reason is u-bolts have a tendency to distort the caps leading to reduced service life. 1350\/1355 series end yokes will have cast  tabs in the yoke saddles to hold the u-joint from lateral movement.\u003c\/p\u003e \u003cp\u003eTwo methods of forging the cross are common. The traditional Hot-Forged cross is cheaper to produce, but the cross hardness is a lower Rockwell value than the more modern and more expensive cold-forged crosses use in premium quality universal joints. Today, greaseable u-joints typically have hot-forged crosses and lubed for life u-joints will usually have cold-forged crosses. For older or lower power applications either cross design should provide satisfactory service, but for later model vehicles with either Diesel or high-torque gas engines we recommend you use premium u-joints with cold-forged crosses.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSpicer 1350 series Driveshaft Universal Joint Specifications:\u003c\/strong\u003e\u003cbr\u003eCap Diameter: 1-3\/16\"\u003cbr\u003eOverall Width of Installed U-Joint: 3.625\"\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAAM 1355 series Driveshaft Universal Joint Specifications:\u003c\/strong\u003e\u003cbr\u003eCap Diameter: 1-3\/16\"\u003cbr\u003eOverall Width of Installed U-Joint: 3.622\"\u003c\/p\u003e","brand":"Identification Help","offers":[{"title":"Default Title","offer_id":41660575154253,"sku":"IDN-142","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0206\/5741\/files\/1350-1355-series-id-1600__30847_7197__44804.1707941561.1280.1280.jpg?v=1742693181"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0206\/5741\/collections\/driveshaft_20identification__26073_3f53af9f-8935-4b81-997f-4da84780a36d.jpg?v=1773182332","url":"https:\/\/torqueking.com\/collections\/1999-2016-driveshaft-identification-ford-sd.oembed","provider":"Torque King 4x4","version":"1.0","type":"link"}
