Why Does the Steering Wheel Suddenly Become Heavy?
2 Answers
Here are the main reasons why a car's steering wheel suddenly becomes heavy: 1. For hydraulic power steering, check if there is a lack of power steering fluid or any oil leakage. If the fluid is low, it needs to be replenished to the normal range. If the fluid level is normal, check if the power steering pump belt is too loose. If it is loose, 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. A leak can also cause the steering to become heavy. If there is a leak, the tire needs to be inflated.
I've encountered the issue of the steering wheel suddenly becoming heavy multiple times. The most common cause is a power steering system failure: the power steering pump may be worn or damaged, resulting in insufficient hydraulic pressure when turning, making the steering heavier. Low or leaking steering fluid is also a common reason; if the fluid reservoir is empty, power assistance fails. A loose or aged drive belt can cause this too, and a slipping belt may produce unusual noises. Low tire pressure can also make handling heavier; remember to check regularly with a tire pressure gauge. Ignoring these issues not only makes steering difficult but may also damage more expensive components. I recommend starting with a simple engine bay inspection: check the steering fluid reservoir level and top it up with the same type of fluid if low, while also checking for leaks; inspect the belt for cracks or looseness. If the problem persists, visit a professional repair shop promptly. Regular maintenance can prevent these issues: for example, check the steering fluid and replace the belt every six months.
