The popularity of this u-joint for 4x4 and light truck applications has been slowly waning since 1979, but it is still used up to the present day in some 1\/2 ton and lighter applications. \u003c\/p\u003e\n\u003cp\u003eA 1310 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. 1310 series end yokes will have cast  tabs in the yoke saddles to hold the u-joint from lateral movement. When used with an end yoke, a 1310 series u-joint may be secured either with u-bolts or strap and bolts. Of the two methods, U-Bolts are usually found on mid-1980s and earlier applications. Since that time, using Strap and Bolts has 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.\u003c\/p\u003e\n\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\n\u003cp\u003e\u003cstrong\u003e1310 series Driveshaft Universal Joint Specifications:\u003c\/strong\u003e\u003cbr\u003eCap Diameter: 1-1\/16\"\u003cbr\u003eOverall Width of Installed U-Joint: 3-7\/32\"\u003c\/p\u003e","brand":"Identification Help","offers":[{"title":"Default Title","offer_id":41660597272653,"sku":"IDN-146","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0206\/5741\/files\/1310-u-joint-id__05820_8377__75560.1707942332.1280.1280.jpg?v=1742694310"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0206\/5741\/collections\/driveshaft_20identification__89507_bda2f771-b9b6-41c8-9903-f43dd9cec6fd.jpg?v=1773182467","url":"https:\/\/torqueking.com\/collections\/1967-1972-driveshaft-identification-gm-rear.oembed","provider":"Torque King 4x4","version":"1.0","type":"link"}
