Yup, mrfixit is probably right. Disconnect both hydraulic lines to cylinder and plug lines. Jack up rear end and move steer axle each way to empty fluid. Force compressed air into one fitting on cylinder and if you feel air flow through other fitting without axle moving, you're bypassing fluid through the center seal.
