ABSTRACT:
A slip spline assembly includes a splined stub shaft slidably received in a splined bore of a yoke member. A sealing plug is provided at one end of the yoke bore to maintain lubricant on the splines and prevent ingress of foreign matter. A plurality of resilient fingers on the plug snap into an annular groove formed in the yoke bore to positively retain the plug. A vent opening in the plug relieves pressure in the closed end of the yoke when the splined shaft slides toward the yoke closed end.
