If you have to work much harder than normal to turn the steering wheel on your car, you are likely facing issues with your power steering assembly. While there are many individual components here, one of the most vulnerable parts is the power steering pump itself. What do you need to know about this particular part, and if it's faulty, can it be repaired, or will it need to be replaced?

How a Steering Pump Works

In simple terms, a conventional power steering pump will pressurise hydraulic fluid to augment the steering rack's turning power. Inside the pump is an impeller that turns at high speed and which gets its power from the engine. The pulley on the outside of the pump holds a belt that is connected to the camshaft. Once the engine is operational, it will provide unlimited power to the steering pump, which, in normal circumstances, will help you turn that wheel.

Replaced Unprepared

Unfortunately, it's not possible to repair a power steering pump if it begins to fail. There are no serviceable parts inside, and it is designed to be replaced when it comes to the end of its usable life. So, you need to be aware of its impending demise so you can take action to replace it before things go badly wrong.

Looking for Tell-Tale Signs

One of the earliest tell-tale signs will be a groaning and whining noise when you try to turn the wheel. This could be down to a lack of steering fluid, which could have leaked out through faulty seals. It could also be due to damaged bearings that support the impeller and pulley. You may also notice a squealing sound when you first start the vehicle. This could be due to the belt slipping as the power is first applied or could indicate that the pump is beginning to fail and does not want to turn.

Sometimes, you may notice a burning smell associated with an overheating pump, but you will inevitably notice the steering is slow to respond, which should prompt you to take action.

Driving with a Damaged Pump

It's never a good idea to drive with a damaged power steering pump. You may find it more difficult to control the car, but if the pump seizes altogether, it could damage the engine. You could even snap the cam belt, resulting in a sizeable repair bill.

Taking Action

So, don't delay any longer if you suspect issues with your power steering pump. Get in touch with a mechanic for further advice on power steering pumps.
