Because the manual steering system is usually designed to be simple, and in some models, the design of the wheel and steering system does not take into account too much power assistance, the manual steering rack needs to bear greater pressure.

Manual steering rack has a simple structure and low cost, but requires the driver to exert greater operating force; while hydraulic steering rack greatly reduces the driver's operating burden through the hydraulic power assist system, but the maintenance requirements are relatively complex and the control feel is slightly reduced.

The answer is no. The manual steering rack does not require a power steering pump, which is one of the fundamental differences between it and the power steering system. The power steering pump is a key component that provides hydraulic assistance to the hydraulic power steering system.

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.
