What Causes the Steering Wheel to be Sometimes Light and Sometimes Heavy?
2 Answers
Generally, it is caused by leakage of the seal responsible for sealing one side of the high-pressure chamber. Another possibility is improper adjustment of the directional limit valve. Correct way to hold the steering wheel: Keep your eyes looking straight ahead. Gently hold the upper left side of the steering wheel with your left hand, and lightly grip the upper part with your right hand, keeping both hands relaxed and naturally hanging down. At this time, the thumbs of both hands should naturally point straight to the upper part of the steering wheel, while the other four fingers should lightly grip from the outside inward. Correct way to turn the steering wheel: Imagine the steering wheel as a clock. When your left hand reaches the 3 o'clock position and your right hand is at the 9 o'clock position, release your right hand. Continue turning with your left hand until it reaches the 6 o'clock position, then have your right hand grasp the 12 o'clock position. Continue turning until reaching the 3 o'clock position, completing one full turn.
Having driven for over twenty years, I find the inconsistent steering wheel weight particularly annoying. Common causes include power steering system failures, such as a loose hydraulic power steering pump belt or oil leakage, resulting in heavy steering at low speeds and light steering at high speeds. Faulty sensors in electronic power steering systems can also cause inaccurate feedback. Uneven tire pressure is another significant factor, so it's advisable to check tire pressure every two weeks to maintain uniformity. Wear and tear on the steering gear or gears can also make the steering feel erratic, especially during turns, which can feel quite dangerous. Regular maintenance, such as checking the steering fluid during oil changes, can prevent minor issues from escalating into major problems. Safety is paramount, so if you notice any abnormalities, don’t delay—seek professional repair immediately.
