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.
