An apparatus (10) for use in turning steerable vehicle wheels includes a rack gear (14) and a sector gear (16) which are disposed in meshing engagement. A housing (30) encloses the rack and sector gears (14 and 16). A sector shaft (22) has an inner end portion (34) connected with the sector gear (16) and an outer end portion (36) disposed outside of the housing (30). A lash adjustment assembly (56) is operable to move the sector gear (16) and shaft (22) relative to the housing (30) to reduce clearance between teeth (18 and 20) on the rack and sector gears. The lash adjustment assembly (56) is manually actuatable at the outer end of the sector shaft (22). The lash adjustment assembly (56) includes an elongated member (60) which extends through the sector shaft (22) and the sector gear (16) into engagement with the housing (30).
