Why does the Vios steering wheel become harder to turn over time?
2 Answers
The Vios steering wheel becoming harder to turn over time indicates that the vehicle is low on power steering fluid. Replenishing sufficient power steering fluid will eliminate the abnormal noise. Steering force standard: Vehicles with mechanical steering have a standard for steering force, generally not exceeding 12 kilograms. The specific value can be measured using a dynamometer during stationary steering by determining the tangential force on the steering wheel. If it exceeds this value, it is recommended to contact a 4S shop for repairs. Power steering fluid: This is a special liquid used in the car's power steering pump. Through hydraulic action, it can make the steering wheel very light to operate, similar to automatic transmission fluid, brake fluid, and shock absorber fluid.
I've been driving a Vios for several years. At first, the steering wheel was very light, but over time it became heavier, especially when parking or turning. This might be due to an issue with the electric power steering system—it's like the car's nerves controlling the steering effort. Over time, the motor or sensors inside may age or fail, reducing the power assistance. Low tire pressure or uneven tire wear can also make the steering feel heavier because the wheels don't turn smoothly. Additionally, steering linkage components may rust or loosen with prolonged use. You should get it checked soon, as driving at high speeds could become unsafe. Remember to maintain regular servicing, including the power steering system and tires, to prevent small issues from turning into big problems. Last time, I discovered low tire pressure caused trouble, but fixing it promptly made a big difference—safety always comes first.
