The steering systems of midsize sedans and SUVs are more complex, and the weight of the rack and pinion steering system may increase slightly. Generally speaking, the steering system weight of such vehicles is about 5 to 7 kilograms.

The gears and racks in the rack and pinion system are metal parts, which will inevitably wear out during long-term use. When the wear of the gears and racks reaches a certain extent, the fit between the rack and the gear may loosen, causing the hydraulic oil to leak from the joint.

When the driver turns the steering wheel, the rotational motion of the steering wheel is transmitted to the pinion through the steering shaft. The rotation of the pinion drives the rack to move linearly, which pushes the wheel to turn left or right. This process accurately transmits the driver's steering input to the wheel to achieve vehicle steering control.

The structure of the recirculating ball steering system is relatively complex, involving screws, nuts, recirculating steel balls and multiple connecting rod components. This complexity makes the system more time-consuming and costly to manufacture and repair. In contrast, the rack and pinion steering system has a simple structure, consisting only of a rack and a pinion, which makes it cheaper to manufacture and relatively easy to maintain.

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.
