Hi there. The issue is not the pump. The pump will fail if the power steering control valve sticks and stops working. The power steering control valve is located in the rack and pinion steering system. If you need further assistance with your power steering not working properly, then seek out a professional, such as one from Your Mechanic, to help you.

Hi there. Quite frequently power steering pump replacement jobs result in air bubbles being trapped in the hydraulic lines. Many professional mechanics utilize a pull-through or vacuum pump system to properly bleed the power steering system. You might want to start your diagnosis by flushing your power steering system first, to see if this helps. If this doesn’t, please have one of our mobile mechanics come to your location and complete a steering wheel is hard to turn inspection.
