Abstract
A constant velocity joint includes a trunnion extending radially outwardly about a trunnion axis. The joint also includes a ball surrounding the trunnion and rotatable relative thereto about a plurality of needle rollers. The joint further includes a retainer that is a single, unitary structure coupled to the trunnion and positioned to limit movement of the ball and the needle rollers in a direction parallel to the trunnion axis.
