Abstract
A power steering apparatus including a rack gear and a pinion gear that are disposed within a housing and preloaded by a yoke assembly. The yoke assembly includes a bushing that is biased into engagement with the rack. A yoke plug extends through a yoke opening to provide a gear mesh load on the rack through the bushing assembly. The yoke body is axially assembled through a rack gear bore in the housing of the steering gear and a yoke assembly is inserted through a yoke bore to apply mesh preload to the bushing assembly. A method of making the yoke assembly by forming leaf springs that are over-molded to form a yoke body.
