The hydraulic pump is the core component of the hydraulic power steering system, which provides power assistance by pressurizing hydraulic oil. If the hydraulic pump fails, such as internal wear or insufficient pressure, the hydraulic system will not work effectively.

Under normal driving conditions, the life expectancy of a rack and pinion is generally 7 to 10 years, or about 100,000 to 150,000 miles (about 160,000 to 240,000 kilometers). This life expectancy is based on daily commuting, good road conditions, regular maintenance, and normal driving habits.

Rack and pinion steering systems can be traced back to the 1930s. In 1932, British car manufacturer Aston Martin first applied the rack and pinion system to its racing models. This design performed well in the racing field at that time, especially in terms of steering accuracy and sensitivity.

When the power steering fluid is insufficient, air may be mixed into the hydraulic system, causing the hydraulic pump to make abnormal noises when it is running. These noises are usually manifested as sharp hissing or whistling sounds, which are more obvious when turning the steering wheel.

If the assembly is not aligned after installation, the wheels may not turn accurately according to the steering wheel's instructions. This may cause the driver to feel that the steering is not sensitive, the steering wheel is tilted, or the vehicle is pulling away when driving in a straight line.

For those car fans who pursue the purest and most direct driving feeling, the mechanical steering system is undoubtedly the best choice. It provides the most realistic road feedback and control feeling, and is suitable for sports driving with high requirements on road conditions.

Water will freeze below 0 degrees Celsius to form ice cubes, which is fatal to hydraulic systems. In cold environments, if water is mixed into the hydraulic system, the system may lose its function due to the freezing of water.

Most standard auto insurance policies do not cover the natural wear and tear or mechanical failure of the rack and pinion due to long-term use. This type of damage is usually considered the owner's responsibility and needs to be repaired at their own expense.

Causes of rack and pinion damage: Vehicle wear and aging Inadequate lubrication of the rack and pinion Failure of the hydraulic system (in hydraulic steering racks) Improper driving habits External shocks and damage

The time required to replace a rack and pinion varies depending on the vehicle model, system design, working environment and technical proficiency. Generally speaking, it usually takes a professional technician 3 to 5 hours to complete this task under ideal conditions.
