Abstract: A rack and pinion steering system includes a rack housing, a rack bearing, and an adjuster plug. The rack housing defines a rack housing bore extending along an axis. The rack bearing is disposed within the rack housing bore. The rack bearing has a first bearing portion that is biasingly connected to a second bearing portion. The first bearing portion and the second bearing portion extend along the axis between a first rack bearing end and a second rack bearing end. The adjuster plug is disposed within the rack housing bore. The adjuster plug extends along the axis between a first adjuster plug end that engages the second rack bearing and a second adjuster plug end.

Abstract: A power steering assembly is provided. The power steering assembly may include a housing, a first bearing, a second bearing, a worm, and a worm gear. The first bearing is disposed within the housing and defines a first central axis. The second bearing is disposed within the housing and defines a second central axis offset from the first central axis. The first bearing and the second bearing are arranged with the housing such that the second bearing is movable to align the first central axis with the second central axis responsive to a load applied to the second bearing.
