Why does the steering wheel suddenly become heavy?
1 Answers
Suddenly heavy steering wheel is caused by low tire pressure or a problem with the power steering system. You should stop and check the tire pressure. If the tire pressure is normal, it indicates a failure in the power steering system, and you should immediately go to a professional repair shop for maintenance. Cars are equipped with power steering systems, and there are three common types: mechanical hydraulic power steering system, electro-hydraulic power steering system, and electric power steering system. Both the electro-hydraulic power steering system and the mechanical hydraulic power steering system have a power steering pump and hydraulic mechanism, and both systems require the use of power steering fluid.
