You likely have air in the system, try turning the wheel side to side and checking the reservoir periodically.

How to repair power steering leak?


You need to first diagnose what is leaking. Most power steering leaks are in the pressure hose but not always. Pressure hoses will have screw on fittings and return hoses will usually just have spring clamps or screw type clamps on the end of the hose. Pressure hose most likely, return hoses 2nd, failing rack and pinion assy 3rd and pressure pump last. If its leaking from the bellows on the end of the rack and pinion the you will need a reman unit. Presure pumps are also remanufactured if thats what you need. hoses are replaced with new hoses or standard return hose for the return line.

Power steering pump shaft broken again


When you place the wheel in a hard lock position ,the power steering pump relies on the pressure by-pass valve to operate instead of the valves in the steering box to open and allow the pressure to by-pass back to the reservoir.. When you hit hard lock and you hear the motor load up just ease on the turn and the pump will operate as designed. The turn will still be the same -just that the pump is not under full load . Breaking the shaft is a sign of excessive load and a misaligned pulley so check that the belt is directly in line and the pump is square to the belt line.
