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.

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.

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.

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.

Steering becomes difficult If the electric power steering rack is damaged, one of the most obvious manifestations is that the steering wheel becomes difficult to turn. This is because the motor cannot provide normal power assistance, and the driver needs to rely on more force to complete the steering operation.

The steering wheel makes abnormal noises when turning, especially "squeaking" or "banging" knocking sounds, which are often early signs of wear or damage to the power steering rack end. When the seals or lubricants at the rack end are lost, friction increases, causing wear between parts, which in turn causes abnormal noises.
