A yoke apparatus for use with a rack and pinion steering system includes a bearing disc member having a bearing surface for supporting the rack and a pair of angled outer surfaces disposed beneath the bearing surface for receiving arms of a biasing member. The biasing member includes a relief spring forming the pair of arms which are encapsulated in resilient material. The biasing member has a bottom surface with at least one recess for receiving a block portion of a support member. The arms of the biasing member compliantly urge the bearing disc into position against the rack while constraining the disc in lateral directions with respect to the housing bore.
