This symptom may suggest that the power steering pump is not generating sufficient hydraulic pressure to assist the steering mechanism.

Another telltale sign is a squealing noise from under the hood, especially when turning the steering wheel. This noise often indicates that the pump struggles to maintain the correct pressure or has a low power steering fluid level. A whining or groaning noise, even when the steering wheel is not being turned, can also point towards a failing power steering pump.

Power steering fluid leaks are another red flag. Visible signs of a leak include spots or puddles under your vehicle and a noticeable decrease in the power steering fluid reservoir. The presence of frothy or discoloured power steering fluid can also indicate that air has entered the system, compromising the pump’s ability to maintain stable hydraulic pressure.

Lastly, a vibrating steering wheel is a less common but potential sign of a problem. If you feel pulsations through the steering wheel, especially when idle or steering, it might indicate issues within the power steering system, including the pump.

Addressing these symptoms promptly can prevent the situation from worsening, ensuring that your Holden Astra remains safe and enjoyable to drive.
