What are the methods to make hydraulic power steering lighter?

[MacSimon]

Methods to make hydraulic power steering lighter: You can replace the power steering fluid with new fluid, which will make the steering wheel feel lighter. If it still feels heavy, it is recommended to check the tire pressure of the front wheels. Low tire pressure in the front wheels can also cause the steering wheel to feel heavy. However, do not inflate the front tires to excessively high pressure just to make the steering lighter, as this will reduce the contact area between the front tires and the road, affecting the vehicle's handling and driving stability. There are two types of hydraulic power steering systems in cars: one is the mechanical hydraulic power steering system, and the other is the electro-hydraulic power steering system. Both types of hydraulic power steering systems have a power steering pump. The power steering pump in a mechanical hydraulic power steering system is driven by the engine, while the power steering pump in an electro-hydraulic power steering system is driven by an electric motor.
