1. An electric power steering system comprising:
a ball screw;
a tie rod having an end region, wherein the tie rod defines a first hole extending along a first axis at the end region, wherein the tie rod defines a second hole extending along a second axis that intersects with, and is substantially perpendicular to, the first axis at the end region; and
a joint assembly operatively coupling the end region of the tie rod to the ball screw, the joint assembly comprising:
a yoke including a first leg and a second leg, wherein each of the first and second legs define a respective hole aligned with each other;
a first pin extending through each of the respective hole defined by the first leg and the second leg of the yoke and through the first hole of the tie rod; and
a second pin disposed in the second hole defined by the tie rod and defining a central hole that the first pin extends through,

wherein the tie rod is rotatable, relative to the ball screw, about the first axis and the second axis, but is prevented from rotation about a longitudinal axis of the tie rod,
