A fluid power assist rack and pinion steering gear assembly (10) includes a torsion bar (70) having a support portion (80) rotatable within an internal bore (60) of an input shaft (50). A circumferential groove (82) is located on the support portion (80) of the torsion bar (70). A compliant ring (90) in the groove (82) engages a cylindrical inner surface (56) in the input shaft (50) to enable rotation of the support portion (80) of the torsion bar (70) within the internal bore (60) of the input shaft while limiting relative radial movement between the support portion of the torsion bar and the input shaft. A hitch pin (100) has a first portion (106) disposed in a hitch pin opening (110) in the pinion (18) and a second portion (112) disposed in a hitch pin opening (116) in a valve sleeve (54). A portion (120, 122) of the material of the valve sleeve (54) is deformed into engagement with the hitch pin (100) to limit relative angular movement between the hitch pin and the valve sleeve about a primary axis (14) of the steering gear assembly (10).
