What Causes a Stiff Steering Wheel?
2 Answers
Reasons for a stiff steering wheel: 1. For hydraulic power steering, the common cause is dirty power steering fluid. Dirty power steering fluid can lead to increasingly heavy steering, and insufficient power steering fluid can also cause the steering wheel to feel heavier. If the issue is related to the power steering fluid, it should be promptly topped up or replaced. 2. For electric power steering, check if any fuses are blown or if there are any short circuits in the wiring. 3. For electric power steering, repeatedly turning the steering wheel while stationary or at low speeds places a significant load on the power steering system, which can easily trigger the steering gear's high-temperature protection, resulting in heavy steering. The steering will return to normal after cooling down, which is a normal phenomenon.
I've been driving for decades and have encountered the issue of a tight steering wheel several times. The most common cause is a problem with the power steering system, such as low power steering fluid or a faulty power steering pump. Hydraulic power steering vehicles are particularly prone to this. Another reason could be insufficient tire pressure, which makes the steering wheel feel heavy and requires extra effort. Additionally, loose suspension components, incorrect wheel alignment, or worn steering parts like tie rod ends can contribute to this issue. When I was younger, I often neglected maintenance, and once the steering wheel became so tight that it nearly caused an accident. I recommend regularly checking fluid levels and tire pressure, and always prioritizing safety while driving.
