Why is the car steering wheel heavy?
2 Answers
The reasons for a heavy car steering wheel are: 1. Power steering pump failure - when the pump pressure does not meet standard values, it can cause a heavy steering wheel; 2. Steering gear failure - when the power steering oil pressure is low, it can result in a heavy steering wheel; 3. Dirty power steering fluid - this may cause the steering wheel to feel heavy; 4. Low tire pressure - can also lead to a heavy steering wheel. Maintenance points for the steering system: 1. For hydraulic systems - ensure the reservoir has sufficient power steering fluid, repair any leaks immediately, and replace the fluid regularly; 2. Avoid turning the steering wheel to its full lock position in daily use, as this may cause excessive oil pressure in the pipes; 3. For electronic power steering systems - specialized equipment is required for inspection.
I feel like the steering wheel is as heavy as pushing a millstone when driving, which is really troublesome. There are many common causes, such as problems with the power steering system. If it's hydraulic power steering, an oil pump leak or low oil level can weaken the assistance; if it's electric power steering, a burned-out motor or a failed electronic control module can also cause this. Additionally, insufficient tire pressure is another annoying issue—low pressure increases friction, making it harder to turn. Don’t overlook the lubrication of the steering shaft; rust or lack of oil can increase resistance. Safety-wise, be careful—a heavy steering wheel can lead to slower reactions, especially when turning, so it’s recommended to pull over and check immediately. Simple self-inspection: pop the hood to see if the power steering fluid reservoir is leaking and check the tire pressure. If you can’t fix it yourself, don’t delay—head to a professional repair shop right away.
