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

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

Hydraulic power steering rack (HPS Rack) is the most common type of steering system in traditional fuel vehicles. Its core is to provide steering assistance through hydraulic pressure. This rack usually works with a hydraulic pump, oil pipe, valve and hydraulic oil tank.

Recalling vehicles: Honda will recall Honda Civics produced between April 6, 2021 and August 17, 2023. Problem: Improper assembly of the Honda Civic's steering rack may cause the tire and/or tire chain to rub against the vehicle's lower suspension or tire rod end, resulting in tire damage.

In hydraulic steering racks, the modulus of the rack and pinion is usually selected within a certain range to balance accuracy, strength and manufacturing cost. Generally speaking, rack and pinion with a modulus between 2 and 4 mm are more common.

When the rack and pinion are loose, the driver may feel that the steering wheel is abnormally loose. When the steering wheel is turned, the response of the vehicle becomes sluggish, and even more turning angles are required to cause the wheels to move.

Generally speaking, the price of the seal itself is not high, usually between $20 and $50. However, since replacing the seal requires disassembling the steering rack, the labor cost is higher, usually between $100 and $300. Therefore, the overall cost may be between $120 and $350.
