The Power Steering Pump pushes the hydraulic fluid into the steering, which helps the driver quickly turn the steering wheel in the desired direction with less force. The primary role of the Power Steering Pump is to reduce the steering turning effort of the driver. Sometimes the Power Steering Pump can stop working or be damaged. Some signs or indicators of Power Steering Pump failure are liquid leakages, noisy mechanical sounds, and difficulty in steering. When the hydraulic fluid starts leaking or the drive belt is damaged, the power assist in the steering immediately stops working.
