How to Make Mechanical Hydraulic Power Steering Lighter?

Methods to make mechanical hydraulic power steering lighter: 1. Replace the power steering fluid with new one; 2. Adjust the driving mode on the vehicle. There are two types of hydraulic power steering systems in vehicles: one is the mechanical hydraulic power steering system, and the other is the electro-hydraulic power steering system. The mechanical hydraulic power steering system is a mechanical hydraulic servo system that operates on the principle of negative feedback control. The main components of the mechanical hydraulic power steering system include a hydraulic pump, oil pipes, a pressure fluid control valve, a V-belt, and a fluid reservoir. This type of power steering converts part of the engine's power output into hydraulic pump pressure to apply an auxiliary force to the steering system, thereby assisting in turning the tires.
Having driven for over a decade, I've found that keeping mechanical hydraulic power steering light mainly relies on routine maintenance. For instance, when the hydraulic fluid gets too dirty or runs low, the steering becomes heavier, so I regularly check the fluid level to ensure it stays between the marked lines. If the oil turns black, it's time for an immediate change. Additionally, a loose or worn power steering pump belt can make steering laborious—simply tightening it yourself or replacing it with a new belt makes a noticeable difference. I've also observed that maintaining proper tire pressure is crucial; underinflated tires increase resistance, naturally making the steering heavier. Some opt for modifications like installing a smaller steering wheel or lighter gears, but careful compatibility with the vehicle model is essential to avoid safety risks. Developing good driving habits, such as avoiding heavy stationary steering, also helps protect the system. These small tips have kept my old car's steering responsive, saving on repair costs while ensuring a comfortable and safe drive.
To make the mechanical hydraulic power steering lighter, the key lies in upgrading critical components. You can try installing a high-performance power steering pump, which has a higher flow rate and provides a lighter steering feel. Alternatively, adjust the rack and pinion ratio to a smaller value, but make sure to have it done by a professional shop to avoid damaging the original parts. Opt for low-viscosity hydraulic fluid, as it flows faster and makes the steering response more sensitive. I remember helping a friend modify his classic car—after switching to full synthetic hydraulic fluid, the steering became noticeably lighter. Also, check for any blockages in the hydraulic lines, and regularly clean the reservoir and filter to ensure smooth fluid flow. Modifications aren’t about reckless tinkering; you need to consider vehicle compatibility and durability. A small investment can significantly enhance driving pleasure, making daily driving as smooth as a brand-new car.
