Abstract: A method of manufacturing a torsion bar for a steering system is provided. The method includes supporting a torsion bar blank on a cold forming machine with a plurality of dies at a first end region of the torsion bar blank and a second end region of the torsion bar blank. The method also includes rolling the torsion bar blank to form an end region having a cylindrical outer surface extending from an axial end surface and a serrated portion disposed proximate the end region and axially offset from the axial end surface.

Abstract: A vehicle steering column assembly includes a first shaft having a first shaft cavity extending from an end of the first shaft. Also included is a second shaft operatively coupled to the first shaft, the second shaft having a second shaft cavity disposed therein. Further included is a torsion bar disposed within the first shaft cavity and the second shaft cavity. Yet further included is a stop tooth extending from the first shaft. Also included is a worm gear defining a slot with a slot wall, a first portion of the slot wall configured to engage a first side of the stop tooth to define a first radial boundary of the worm gear, a second portion of the slot wall configured to engage a second side of the stop tooth to define a second radial boundary of the worm gear.
