BUICK EXCELLEGT LHD 90921853 Manual steering rack

BUICK EXCELLEGT LHD 90921853 mechanical steering rack is an important steering component designed for Buick Excelle models, mainly used for left-hand drive models (LHD). The design and structure of this product fully consider the vehicle's needs for steering sensitivity, accuracy and reliability during driving, and is particularly suitable for vehicles with manual steering systems, that is, mechanical steering, rather than the hydraulic or electronic power steering systems commonly found in some modern models.

BUICK EXCELLEGT steering rack overview

Product name: BUICK EXCELLEGT LHD 90921853 mechanical steering rack

Applicable models: Buick Excelle

Product type: mechanical steering rack

Applicable driving mode: Left Hand Drive (LHD)

OE number: 90921853 (this is the general part number of this product)

The mechanical steering rack is one of the core components of the vehicle steering system, responsible for transmitting the steering force of the steering wheel to the wheels, so that the vehicle can steer according to the driver's intention. In the absence of a power-assist system, the mechanical steering rack relies on the driver's manual operation for steering control. Its working principle is relatively simple and reliable, and does not involve hydraulic or electronic components, reducing the possibility of maintenance and failure. Especially in driving conditions that require a high degree of steering feedback, the mechanical steering rack can provide a more direct driving experience.

Technical parameters and functions of BUICK steering rack

1. The significance of OE number 90921853

This OE number is the official part number assigned by General Motors for this mechanical steering rack, which can help repair personnel and parts suppliers quickly locate and provide the correct replacement parts. This number ensures the precise fit and compatibility of the product with Buick Excelle models, and can be installed exactly the same as the original parts.

2. Applicable models and driving styles

BUICK EXCELLEGT, that is, Buick Excelle, is a popular mid-size sedan designed to meet the needs of the global market. This mechanical steering rack is designed for left-hand drive models (LHD), which means that this product is particularly suitable for use in left-hand drive countries and regions, such as mainland China, most European countries and the United States.

3. Mechanical steering system vs. hydraulic/electronic power steering system

This BUICK steering rack is a mechanical steering rack. Unlike hydraulic or electronic power steering systems, it relies on the driver's power to directly control the vehicle's steering. Although the mechanical steering system requires more force when steering, its advantages are simple system, low cost and strong durability, which is particularly suitable for drivers who have high requirements for driving feedback or car owners who are sensitive to maintenance costs. Mechanical steering rack has the following advantages:

    ● High reliability: Since there are no hydraulic or electronic components, it is not easily affected by problems such as oil leakage and circuit failure.

    ● Simple maintenance: The mechanical structure is relatively simple, the parts wear less, and the later maintenance cost is low.

    ● Accurate steering feedback: The mechanical system can provide a direct steering feel, and the driver can clearly feel the road conditions.

4. Working principle of steering rack

The steering rack is a gear-rack structure. The steering wheel is connected to a small gear (steering gear). When the driver turns the steering wheel, the gear drives the rack connected to it to move in a specific direction. This mechanical movement is transmitted to the steering rod connected to the rack, which controls the steering angle of the front wheels. The whole process does not rely on hydraulic pressure or motor assistance, but is completely completed by the driver's manual operation, so the driver can get a purer steering experience.

5. Installation and Compatibility

This mechanical steering rack is perfectly compatible with the original steering system of Buick Excelle, and no additional modifications or adjustments are required during installation. Its size and installation position are exactly the same as the original parts, which can ensure seamless connection with the rest of the vehicle after replacement. In addition, this product has undergone strict quality control and testing to ensure that it can maintain stable performance under various driving conditions.

6. Product application scenarios

This mechanical steering rack is suitable for use in a variety of driving environments such as urban roads, rural roads, and highways, especially for drivers who do not rely on hydraulic power or electronic systems. It is particularly suitable for drivers who have high requirements for driving feel, such as some owners who like a more "original" driving experience. They may think that the feedback of hydraulic or electronic power systems is too vague, while mechanical systems can provide more direct and real feedback.
