If there is air in the system, the hydraulic oil cannot stably provide sufficient power support, resulting in heavy or slow response when steering, especially when steering at low speeds or parking, the owner will obviously feel the difficulty of steering.

If the engine cannot operate normally, the hydraulic pump cannot continue to work. When the hydraulic pump cannot provide sufficient hydraulic power, the performance of the hydraulic power steering system will be greatly reduced, resulting in insufficient steering power.

The hydraulic oil should be kept in the pipes and steering rack inside the system, and should not flow out through the dust cover. If there is liquid outflow or accumulation in the dust cover, it usually means that there is a problem with the steering system, which may involve aging, damage or oil seal failure of the seal.

If the hydraulic oil is found to be contaminated or leaking, it may mean that the pump has also been damaged to a certain extent and needs to be inspected or replaced. Otherwise, continuing to use a bad pump will affect the long-term stability and performance of the steering system.

Unlike engines or gearboxes, hydraulic power steering racks do not need to be run-in by running at low speed for a long time. The meshing surface between the steering rack and the pinion is usually precisely processed during the production process, and the degree of fit is high.

One of the biggest advantages of hydraulic power steering rack is improved handling performance. Traditional mechanical steering systems achieve steering by directly connecting the steering wheel and wheels, requiring the driver to apply greater force, especially at low speeds or parking.

In general, the impact of the failure of the electric power steering rack on the vehicle's controllability after the loss of power assistance is more direct and serious, and it is usually more dangerous. Therefore, car owners need to attach great importance to the maintenance and inspection of the electric power steering rack.

Although hydraulic power steering racks were once the mainstream choice for automotive steering systems, with the advancement of electronic technology, other types of steering systems have gradually occupied an important position in the market. However, this does not mean that hydraulic power steering racks have been completely eliminated.

If you often drive on the highway and need stable directional control and less fuel consumption, the electric power steering rack is still the first choice. It can provide consistent power assistance to ensure stability when driving at high speeds.

In general, it is recommended that car owners replace the steering fluid every 2-3 years or every 50,000 kilometers. Of course, the specific replacement cycle should also refer to the recommendations of the vehicle manufacturer.
