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

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.
A leaking steering gear doesn't necessarily require complete replacement—it depends on the severity and cause of the leak. In many cases I've encountered, minor seepage is often caused by aging seals, where replacing the seal for a few hundred dollars suffices. However, with severe leaks (e.g., visible oil dripping daily or low power steering fluid), steering becomes heavier or even fails, posing serious risks—especially on curves or highways—so prompt action is crucial. I recommend first identifying the leak source: loose hose fittings or seal failure. Minor fixes save money, while major issues warrant replacement for safety—never delay repairs.
Never ignore power steering fluid leaks as they pose safety hazards. Leaking fluid causes unstable power steering operation, making the wheel harder to turn and increasing the risk of losing control in emergencies. I remember helping a friend inspect his car - we caught a minor seepage early and fixed it by replacing the oil seal. But if the fluid is nearly drained, you must replace the entire steering gear as a precaution. Regularly check fluid levels and address issues promptly for peace of mind. Don't risk safety to save small money - safe driving comes first.
