ABSTRACT:
A tool for use in the lubrication of a slip joint formed by a spline connection between a shaft and a sliding yoke in a two piece vehicle driveline. The tool includes a pair of spring brackets having legs which grip the yoke. An L-shaped spring arm has one end connected to a rigid plate secured to the brackets. The other end of the spring arm carries a plug having a conical tip which plugs a vent hole in the yoke when lubricant is applied to the slip joint. The spring arm holds the plug in the vent hole to assure a complete fill of the slip joint with lubricant and yields if necessary to relieve excessive pressure which could damage the slip joint seal.
