Abstract: A rack and pinion steerig gear (10) comprises a housing (12). A yoke assembly (40) is inthe housing (12) for at least partially supporing and guding movement of a rack bar (34) relative to a pinion gear (26). The yoke assembly (40) comprises a yoke (42) and a plurality of rotatable members. The yoke (42) has a first end surface (48) and an axis (A) that extends transverse to teh direction of movement of the rack bar (34). Each of the plurality of amembers is supported by the yoke (42). A portion of each rotatable member projects outwardof the first end surface (48) of the yoke (42) for contacting the rack bar (34). Each rotatable member is rotatable aout its axis and is fixed against movement along the yoke axis (A) relative to the yoke (42).
