Title Drive Line Slip Joint Assembly Abstract of the Disclosure A drive line joint assembly 10 has splined driving and driven members 13,20, one of which has a protuberance 36 which extends axially along a spline 16,18 thereof to insure the absence of radial tolerance for balancing purposes. In a preferred form, a forged steel spline 16 has a resilient coating 40 bonded thereto, the coating preferably of a nylon or of other material having comparable low friction quality. The resilient protuberance is an integral part of the latter low friction coating and is formed by a broaching tool after the coating material has been applied to the spline. In a preferred embodiment, the protuberance extends only 0.001 to 0.003 inch above the surface of the coating, wherein the coating has a thickness in the range of 0.007 to 0.014 inch over the steel body portion of the spline. At least three of the protuberances are preferred, each circumferentially spaced from the other. The protuberances are utilized to take up all radial slack between driving and driven members of the drive line joint assembly, thereby allowing for no radial movement of one member with respect to the other.
