What Causes the Steering Wheel to Become Heavier?
2 Answers
There are several reasons why a car's steering wheel may become heavier: 1. For hydraulic power steering, check if the power steering fluid is low or if there is any leakage. If the fluid is low, top it up to the normal range. If the fluid level is normal, check if the power steering pump belt is too loose. If it is, tighten the belt. Also, check if the fluid is too dirty, which can reduce its flowability. Generally, the fluid should be replaced every 2 years or 60,000 kilometers. 2. For electric power steering, check if the fuse is blown and if there are any open circuits or short circuits to ground in the wiring. 3. Check the tire pressure, as low pressure can also make the steering heavier. If the tires are underinflated, inflate them to the recommended pressure.
I've encountered many cases where the steering wheel becomes heavier, mainly due to issues with the steering system. For hydraulic power steering, a faulty power steering pump or insufficient power steering fluid can directly make steering more laborious. In electric power steering vehicles, control system or sensor failures might cause the steering wheel to feel heavier. Low tire pressure is also a common culprit, as it makes steering more difficult, especially noticeable when turning. Additionally, incorrect front wheel alignment or worn suspension components, such as loose steering linkage, can affect steering effort. If you notice this issue, I recommend first checking the tire pressure yourself with a gauge. If that's not the problem, it's best to have a professional shop conduct a thorough inspection. Ignoring it could lead to unresponsive steering, increasing the risk of losing control and causing an accident, which is particularly dangerous at high speeds when handling capability diminishes. Regular maintenance, like topping up power steering fluid or checking sensors, can prevent many of these issues.
