Is it necessary to replace the car steering gear if it's leaking oil?

[SanCody]

It is not always necessary to replace the car steering gear if it's leaking oil. If the leakage is minor, you can temporarily ignore it and continue driving. However, if the leakage is severe, it is recommended to replace it directly. In vehicles equipped with power steering systems, the energy required for steering is mostly provided by the hydraulic (or pneumatic) energy from the oil pump (or air compressor) driven by the engine (or motor), with only a small portion coming from the driver's physical effort under normal conditions. The power steering system converts part of the mechanical energy output by the engine (or motor) into pressure energy and, under the driver's control, applies hydraulic or pneumatic forces in different directions to the steering transmission or a component in the steering gear to assist when the driver's effort is insufficient. Collectively, these components are referred to as the power steering gear.
