Natural wear and aging are one of the most common reasons for replacing a power steering rack and pinion set. The rack and pinion will constantly rub against each other during long-term use, and although they are usually made of high-strength materials, they will inevitably wear out.

A rack and pinion steering system is a mechanical steering system that uses the interaction of a rack and pinion to convert the rotational motion of the steering wheel into lateral movement of the wheels. This relatively simple design is very efficient and has been widely used in many vehicles, including cars, SUVs and light trucks.

Although the basic design of the two is similar, the steering ratio of the power system is usually designed to be lower due to the addition of the power system, while the manual system tends to have a higher steering ratio.

The following are some common names for hydraulic steering gears: 1. Power Steering System 2. Assisted Steering 3. Hydraulic Power Steering System 4. Rack and Pinion Steering 5. Hydraulic Assist System

If the leakage is caused by wear of the rack or pinion, then the difficulty of repair will be relatively large. The worn rack surface may cause the seal to fail to seal effectively, which in turn causes hydraulic oil leakage.

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.

When the driver hears abnormal squeaks or grinding noises when turning the steering wheel, this is often a sign of worn or insufficient lubrication of the rack and pinion. If these noises persist and become more severe, it may mean that the rack and pinion are damaged and need to be replaced.

Typically, the life of a rack and pinion is 100,000 miles to 150,000 miles (about 160,000 kilometers to 240,000 kilometers). However, this does not mean that all vehicles can reach this mileage, and it is possible that wear or failure may occur before or after this.

Selected innovative model: Citroën 2CV The Citroën 2CV was the first car in the world to use a rack and pinion steering system extensively. The car debuted at the Paris Motor Show in 1948 and became a major highlight of the automobile market at the time.

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.
