What are the hazards of not changing power steering fluid?

Failing to replace the power steering fluid (PSF) in a timely manner can lead to damage to the steering gear and power steering pump. Here is more information about power steering fluid: 1. Power steering fluid is a special liquid used in the car's power steering pump, which, through hydraulic action, makes the steering wheel lighter. It is similar to automatic transmission fluid, brake fluid, and shock absorber fluid. 2. To prevent the power steering fluid from becoming too dirty or deteriorating, it is generally recommended to replace the power steering fluid every 2 years or 30,000 kilometers. If the power steering fluid is found to be below the scale, becomes thin, or the color turns black, it indicates that it is time to replace the power steering fluid.
I learned this lesson the hard way with my old car. The most immediate effect of not changing the power steering fluid for a long time is that the steering wheel becomes noticeably heavier. I drove over 60,000 kilometers without changing it, and in winter, the steering would creak, while in summer, turning became significantly more strenuous. When I took it to the repair shop and they opened it up, the fluid had turned into a black, paste-like substance full of metal shavings. The mechanic said that once the fluid deteriorates, its lubricating properties vanish, causing double the wear on the steering gear's components. The scariest moment was when I was taking a high-speed curve, and the steering wheel suddenly stuck for half a second—it gave me a cold sweat. The hydraulic power steering system relies entirely on this fluid to transmit pressure, and when it ages, it can also corrode the seals. Fixing a leak caused by this can cost over 2,000 yuan. It's recommended to change it at least every two years or 40,000 kilometers.
