Steering fluid is required for Hydraulic Power Steering (HPS) and Electronic Hydraulic Power Steering (EHPS). This is because these systems rely on hydraulic fluid to generate pressure to assist in steering operations. In Electronic Power Steering (EPS), steering fluid is not required.

Manual steering racks are significantly different in structure from hydraulic steering racks, so direct replacement is not always possible. Installing a manual steering rack may require modifications to the vehicle's suspension system and steering column to ensure compatibility between the two.

The power steering rack is connected to the steering gear and steering wheel, and is responsible for converting the driver's steering instructions into actual steering actions of the wheels. Traditional mechanical steering requires a lot of force, while the power steering makes steering easier.

Steering rack is core of the steering system.Just like a heart for human. It promise you a better driving experience.
