An electric power steering drive pulley assembly includes a motor shaft. The pulley assembly also includes a drive pulley coupled to the motor shaft. The drive pulley includes a radial retention portion having an inner diameter defining a first portion of a central opening that the motor shaft is disposed within. The drive pulley also includes an axial retention portion extending in the axial direction from the radial retention portion, the axial retention portion defining a second portion of the central opening that the motor shaft is disposed within, the inner diameter of the axial retention portion in splined engagement with the motor shaft to rotationally couple the drive pulley to the motor shaft, the axial retention portion including a flange protruding radially inwardly from the inner diameter of the axial retention portion to be disposed in a groove of the motor shaft.

A travel stop support bushing includes a body and an extension. The body has a first outer surface that extends between a first body face and a second body face along an axis. The body defines a plurality of fins that are at least partially defined between the first outer surface and the second body face. The extension has a second outer surface that extends between the first body face and an end face.

A steering system is provided. The steering system may include a drive pulley and a ball nut assembly. The drive pulley may be operatively connected to a drive shaft. The ball nut assembly may be driven by the drive pulley via a belt disposed about the drive pulley and the ball nut assembly. The ball nut assembly may include a ball nut and a driven pulley. The ball nut may have an inner surface disposed about a ball screw that defines and extends along a first axis and an outer surface disposed opposite the inner surface. The ball nut may define a first groove that extends from the outer surface towards the inner surface. The driven pulley may be disposed about the ball nut and have a retaining member that includes a finger for extending into the first groove to engage the ball nut and driven pulley without separate fasteners.
