Abstract
A slip joint for a driveshaft having first and second universal joint yokes includes a first shaft extending rearwardly of the first yoke and rotatable therewith and a second shaft extending rearwardly of the second universal joint yoke and rotatable therewith. The shafts have external and internal splines to enable slidable but nonrotatable movement between the shafts. A sleeve extends rearwardly from the first yoke around the first shaft and a portion of the second shaft. The second shaft has two seals extending therearound and engagable with the interior surface of the sleeve. The first shaft has a bore extending completely therethrough and communicating with passages at both ends of the shaft. A lubricant is applied to the splines prior to assembly and a vent opening is plugged with the yokes in the middle position after assembly. The slip joint is completely maintenance free, never needing lubrication.
