A stroking constant velocity universal joint assembly is provided including a drive member having a plurality of circumferentially spaced rotatable drive elements, and a drive housing disposed about the drive elements. The drive housing has an inner wall formed with a plurality of circumferentially spaced drive channels. The drive channels have running surfaces extending axially of the housing to an open end thereof and which guide the rotatable drive elements for stroking movement within the drive housing. A retainer assembly is provided including a ramped surface extending along each drive channel for gradually narrowing a span of the drive channel, to maintain a respective drive element within the housing. In another aspect of the invention, a retainer assembly is provided for retaining a drive member within a drive housing of a stroking universal joint. The retainer assembly includes a base portion and a plurality of ears projecting from the base portion. Each ear has a first surface and a second surface opposite the first surface, the second surface being inclined with respect to the first surface. The second surface is adapted for engaging a portion of the drive member to retain the drive member within the drive housing.
