Abstract
A power steering assembly includes an electric motor having an output shaft extending therefrom. The assembly also includes a housing containing a worm gear operatively coupled to a steering shaft, the worm gear rotatable about a worm gear axis. The assembly further includes an electric motor and a worm arranged to engage the worm gear, the worm extending from the output shaft of the electric motor as a single, integrally formed shaft, the single, integrally formed shaft extending axially from a first end to a second end and being cantilevered to allow the second end to deflect. The assembly yet further includes a bushing surrounding a portion of the shaft proximate the second end of the shaft, the bushing and the portion of the shaft defining a clearance therebetween.
