A hydraulic power steering gear (,) comprises first and second relatively rotatable valve members (,and,). The first valve member (,) has a radially extending first passage (,) and a second valve member (,) partially encircling the first valve member. The second valve member (,) has a cam surface (,) facing radially inward. The first and second valve members (,and,) are rotatable relative to one another to selectively port hydraulic fluid. A ring member (,) is fixedly attached to the first valve member (,). The ring member (,) has a radially extending first bore (,) radially aligned with the first passage (,). A detent member (,) acts between the first and second valve members (,and,). The detent member (,) is disposed in the cam surface (,) in the neutral condition to provide a physically perceptible indication to a driver of the vehicle of operation of the steering gear (,) between the neutral condition and the actuated condition. A spring (,) biases the detent member (,) radially outward. The spring (,) is disposed in the first passage (,) in the first valve member (,).
