Power steering noises when engine is hot

I've noticed over the last couple of days that when my engine has been running for a while, I get a really noticeable wirring noise when I turn the wheel but also driving in a straight line and accelerating I get the same buzzy/ wirring noise.

 

The level of fluid was fine. Am I going to need a new pump?

The PS fluid should be a nice and clean. I had a noticeable notchiness in my power steering and the oil smelt a bit off so a change and all was well. Draw a bit of oil out and check it looks and smells good as a change out would be the cheapest solution to any problem.

Take the reservoir off and wash it out *WELL* with petrol or brake cleaner. Then blow out with compressed air and wash out again. There's a nylon gauze as a filter near the bottom of it . DO NOT POKE AT IT, you'll easily puncture it!! They clog up with sediment and the pump cavitates and makes a noise such as you describe. Similarly if the suction hose from pump to reservoir is hard and leaky, or the O ring on the pipe adaptor to the pump body is hard, the pump can draw air and make a noise. Either situation will slowly erode the pump body and vanes, making a rebuild very costly. So it needs fixing ASAP.

Thank you for that advice. I've stopped using the car as soon as it started, so I don't exacerbate the problem until I find a solution.

I will give this a go at the weekend. Thank you
