Abstract: 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.

Abstract: A tuner hose assembly for a motor vehicle power steering system including a flexible hose, a first flexible tuner tube inside the flexible hose having an upstream end connected to a pump, and a second flexible tuner tube inside the flexible hose having a downstream end connected to a power steering gear. A downstream end of the first flexible tuner tube is longitudinally separated from an upstream end of the second flexible tuner tube by a wave interference gap which terminates where an inner wall of the flexible hose is clamped against the upstream end of the second flexible tuner tube. The length of the second flexible tuner tube is selected, i.e. "tuned", to attenuate higher order pump fluid-borne noise and simulates a rigid metal tube of a prior tuner hose assembly having greater overall length.
