Whether a car is equipped with power steering depends on many factors, including the type of car, the nature of the competition, and the needs and preferences of the drivers. Although power steering can reduce driver fatigue and improve handling stability, it can also increase the weight and complexity of the vehicle and reduce steering feedback.

When the power steering system fails, the driver needs to rely on more manual force to turn the steering wheel, especially when driving at low speeds or parking. Without power assistance, the steering wheel becomes extremely heavy to turn, which is a big challenge for some drivers with less power.

When the hydraulic power steering rack becomes loose, the response of the steering wheel may become sluggish. When the driver turns the steering wheel, he does not feel the immediate response that should have been there, but needs to spend more force or time to complete the steering operation.

The first large-scale application of electric power steering was in 1993, when Italian car manufacturer Fiat introduced this innovative technology on its Punto model. The Fiat Punto was the world's first mass-produced car equipped with electric power steering.

Through the above analysis, it can be concluded that not all steering racks require hydraulic oil. Specifically, the steering racks of manual steering systems and electric power steering systems do not require hydraulic oil, while the steering racks of hydraulic power steering systems rely on hydraulic oil to provide steering assistance.

Chevrolet officially launched the power steering system in 1953. This time point is of great significance, marking an important step for Chevrolet in technological innovation. In 1953, Chevrolet's representative model, the Chevrolet Corvette, was launched as the brand's first two-seater sports car.

some manufacturers recommend replacing the steering fluid every two years or every 40,000 to 50,000 kilometers. Owners should first refer to the recommendations in the vehicle manual and follow their instructions for replacement.

Advantages of hydraulic power steering system: Provides stable and powerful steering assistance Sensitive feedback and precise control Strong adaptability, suitable for a variety of vehicles High stability and reliability Relatively low cost Disadvantages of hydraulic power steering system: Low fuel efficiency Large volume and increased weight Complex maintenance and many vulnerable parts Inferior control feel to mechanical steering High noise

Hydraulic power steering racks can significantly improve the controllability of trucks and reduce the labor intensity of drivers. For large trucks that are driven for a long time, hydraulic power steering racks make it easier to operate the steering wheel and avoid fatigue caused by long-term steering burdens.

The operation between the rack and the pinion depends on adequate lubrication. When the power steering fluid is exhausted, this lubrication function fails, resulting in excessive friction between metal parts and abnormal wear. The gear portion of the rack will be damaged due to direct contact, and eventually the steering rack will fail.
