If the hydraulic oil is not replaced or cleaned in time, it may cause wear, corrosion or blockage of components such as the steering pump and steering rack, which will affect the normal operation of the steering system. Therefore, regular replacement of hydraulic oil and cleaning of the hydraulic system have become necessary measures to ensure the efficient operation of the hydraulic power steering system.

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.

Carbon steel is one of the most common materials for manufacturing power steering racks. Its advantage is that the cost is relatively low and it has good processing performance. Carbon steel has high hardness and wear resistance, which can meet the requirements of steering racks for load capacity and durability.

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.

In other words, after the car is turned off, although the hydraulic system no longer maintains pressure, the hydraulic fluid in the system may continue to leak due to gravity or residual oil pressure. In particular, power steering fluid is more likely to leak in the following situations: 1. There is a small leak in the system 2. Leakage caused by pressure release 3. The influence of parking posture:

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.

Here are some common reasons that may cause power steering whining: 1. Air entering the hydraulic system 2. Aging or damaged power steering pump 3. Loose or worn belts 4. Clogged or damaged hydraulic lines 5. Fluid deterioration or contamination 6. Wear of internal components of the steering system

After entering the 21st century, with the rapid development of electric power steering (EPS) technology, the power steering system has undergone changes again. The electric power steering system no longer relies on hydraulic oil, but directly provides power to the steering wheel through an electric motor, making steering more precise and efficient.
