From Toyota and Ford to BMW and Mercedes-Benz, these brands still choose hydraulic steering systems on some models because of their excellent reliability, excellent driving feedback and low manufacturing and maintenance costs.

The driver needs to exert more force when steering, which is especially dangerous for inexperienced drivers. In an emergency, the lack of steering power may cause the vehicle to fail to avoid obstacles in time or make correct steering operations, causing accidents.

A damaged steering rack may cause inaccurate steering of the vehicle. This phenomenon is usually manifested as the actual steering angle of the vehicle does not match the expected one after the driver turns the steering wheel, or the steering response is slow.

In some cases, the oil leakage problem of the hydraulic steering rack may be caused by the design defects of the vehicle itself. For example, the hydraulic steering system design of some models is not reasonable, resulting in excessive hydraulic oil pressure or excessive stress on the seals, thereby increasing the risk of oil leakage.

The main function of the power steering pump is to provide hydraulic pressure and is the "heart" of the system. The power steering rack is the actuator, which converts hydraulic pressure into mechanical movement and is the "hands and feet" of the system. The pump provides power support for the rack, while the rack converts this power into actual steering effect.

Reasons for noise in the hydraulic power steering system: 1. Insufficient hydraulic oil or oil mixed with air 2. Power steering pump failure 3. Steering rack failure 4. Poor quality or deterioration of hydraulic oil 5. Loose pipes or joints 6. Excessive pressure caused by the steering wheel hitting the bottom

The performance of a repaired power steering rack depends on the quality of the repair and the severity of the problem. In some cases, the repair may not fully restore the original performance of the rack, especially when the internal mechanical parts are already severely worn.

In general, the service life of the hydraulic power steering rack is between 120,000 and 150,000 kilometers. However, this value is not absolute, because different use conditions will have different effects on its life.

If the steering rack leaks seriously, the owner may find obvious oil traces under the vehicle or near the steering rack. These oil traces are usually light yellow or amber in color and have a certain viscosity.

New energy vehicles, especially pure electric vehicles, usually choose electric power steering systems when designing their power steering systems. The main reasons are as follows: Energy matching of electric power steering systems Efficient energy use Simple structure and high reliability
