To make your power steering lighter, the primary method involves adjusting the steering rack, which can be done electronically or mechanically after removing it.
Power steering systems are designed to assist drivers in turning the steering wheel, reducing the physical effort required. While manufacturers set a specific level of assistance, it is possible to modify this level to make the steering feel lighter. This adjustment is even offered as a factory option on some vehicles.
According to the provided information, lightening power steering involves:
- Removing the Steering Rack: The central component responsible for translating steering wheel input into wheel movement needs to be accessed.
- Adjusting the Steering Rack: Once removed, the rack can be adjusted. This adjustment can be performed:
- Electronically: For modern vehicles with electronic power steering (EPS), software or control module modifications might alter the level of assistance provided.
- Mechanically: For hydraulic or electro-hydraulic systems, internal components of the steering rack might be modified to change the pressure or flow characteristics, thereby altering the steering effort.
By performing these adjustments, the effort required to turn the steering wheel can be reduced by varying amounts, resulting in lighter steering feel.
Important Considerations:
- Complexity: This process typically requires specialized knowledge and tools, often involving professionals familiar with steering system modifications.
- Cost: Adjusting or modifying a steering rack can be a significant expense.
- Impact on Handling: Making steering excessively light might reduce road feel and could potentially impact handling characteristics and driver confidence at higher speeds.
- Vehicle Compatibility: While possible on "most vehicles," the feasibility and method can vary greatly depending on the make, model, and year of the car, particularly the type of power steering system installed (hydraulic, electro-hydraulic, or electric).
Before attempting such modifications, it's advisable to consult with automotive professionals or specialists experienced in steering system tuning to understand the potential outcomes and ensure the work is done safely and correctly.
