An electric power steering assembly for a steering column includes a lower assist shaft defining a first bore. The assembly also includes a needle bearing at least partially disposed within the first bore. The assembly further includes an upper assist shaft assembly defining a second bore and having a journal surface at an end thereof. The assembly yet further includes a torsion bar having a first end disposed in the first bore and a second end disposed in the second bore, the torsion bar having a torsion bar run-out that forces the journal surface to remain in contact with an inner surface of the needle bearing.

A power-assisted steering system includes a control shaft arranged along a control shaft axis. An assist drive shaft defines a drive shaft axis and is arranged in a plane that is substantially transverse to the control shaft axis. The assist drive shaft is supported relative to the vehicle structure by a first bearing assembly and a second bearing assembly. A worm is disposed about the assist drive shaft. A worm gear is coupled to the control shaft, and the worm gear and control shaft are configured for rotation about the control shaft axis. The worm gear is configured for engaging the worm such that rotation of the worm and the assist drive shaft about the drive shaft axis causes rotation of the worm gear and the control shaft about the control shaft axis. The first bearing assembly is configured as an eccentric bearing assembly.
