Yes, a grinding noise while turning the steering wheel is a common symptom of a failing power steering pump. The pump is responsible for providing hydraulic pressure to the power steering system, which allows you to turn the steering wheel with less effort. When the pump fails, it can no longer provide the necessary pressure, which results in a grinding noise. Other symptoms of a failing power steering pump include:
- Difficulty turning the steering wheel
- A whining or squealing noise from the pump
- Leaking power steering fluid
- A burning smell coming from the pump
If you are experiencing any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic. A failing power steering pump can be dangerous, as it can cause you to lose control of your vehicle.
