The Buick brand truly applied the power steering system to mass-produced models on the Buick Roadmaster launched in 1952. As the flagship model of the Buick brand at the time, Roadmaster represented Buick's highest level in the field of luxury cars.

The main components of power steering fluid are mineral oil or synthetic oil, which become more flammable in high temperature environments. When power steering fluid leaks into the engine compartment or the bottom of the vehicle, especially near hot parts such as the exhaust pipe, engine, spark plugs, etc., there is indeed a potential risk of causing a fire.

When water enters the power steering system, it will have an adverse effect on various components of the system. This is because the hydraulic oil in the power steering system not only needs to play a lubricating role, but also needs to maintain the hydraulic pressure of the system and provide power assistance.

The rack and pinion steering system can provide high accuracy and stable controllability due to its precise gear meshing design. For four-wheeled motorcycles, this high-precision steering system can ensure that the driver can still maintain a good control experience in off-road or complex road conditions.

When the electric power steering system fails, the driver may immediately feel that the steering wheel becomes very heavy, especially when driving at low speed or parking. This phenomenon is particularly obvious.

Long-term use of leak-stoppers may cause seals to swell or harden, further compromising the system's seal. While leak-stoppers may appear effective in the short term, over time, seal degradation will lead to larger leaks and even more expensive repairs.

The power steering pump is an important component in the power steering system of a car. Its main function is to provide power assistance through the hydraulic system, allowing the driver to turn the steering wheel more easily. In other words, the power steering pump is responsible for converting the mechanical energy of the engine into hydraulic energy, thereby reducing the force required for steering.

In general, the impact of the failure of the electric power steering rack on the vehicle's controllability after the loss of power assistance is more direct and serious, and it is usually more dangerous. Therefore, car owners need to attach great importance to the maintenance and inspection of the electric power steering rack.

Given the strict requirements of F1 cars for the steering system, the application of traditional rack and pinion steering systems in F1 cars is not entirely applicable. However, the steering system of F1 cars can still be regarded as a high-performance variant of the rack and pinion system.

In the first few generations of Buick LaCrosse models, Buick chose the hydraulic power steering system. With the continuous advancement of automobile technology, the electric power steering system has gradually become mainstream, and Buick LaCrosse has also followed this trend.
