Why is the steering wheel of small cars becoming increasingly heavy?
2 Answers
The reason why the steering wheel of small cars is becoming increasingly heavy may be due to excessively tight bearing fit, or faults in the steering gear and power steering pump. Below is more information about car steering wheels: 1. Introduction: The steering wheel is generally connected to the steering shaft via splines, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. The steering transmission shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel on the vehicle more reasonable. 2. Fault diagnosis: Drive at a speed of 15 kilometers per hour, and while driving, turn the steering wheel left and right to check whether the steering wheel is flexible and whether there is a lack of return force. After releasing the steering wheel, observe whether the vehicle tends to deviate from its path.
A few days ago, the steering wheel of the small car I was driving suddenly became heavy, making it really hard to drive. I thought about it for a while and figured it might be a problem with the power steering system. Since the car is old, it could be due to hydraulic fluid leakage or degradation, causing the power steering pump to underperform, especially noticeable during cold starts. Low tire pressure is another common reason—you should regularly check if the pressure in all four tires is at the recommended level, as too low pressure increases steering resistance. Worn steering linkage or ball joints, or rusted metal parts getting stuck, can also make the steering heavier. I suggest not delaying and getting it checked at a repair shop promptly to avoid worsening the issue and compromising driving safety. Remember to regularly maintain the power steering fluid and tires—these small details can save a lot of trouble.
