What Causes the Steering Wheel to Suddenly Become Heavy?
1 Answers
The reasons for the steering wheel suddenly becoming heavy are: 1. Dirty or leaking hydraulic power steering fluid; 2. Flat tire causing unstable tire pressure; 3. Blown fuse in the electric power steering system; 4. Overly tight fit between the rolling bearings connected to the steering system, leading to poor bearing lubrication and sticking; 5. Malfunction of the steering gear or power steering pump. Power steering assists the driver in adjusting the car's direction, reducing the effort required to turn the steering wheel, and plays a role in the safety and fuel efficiency of the vehicle. The power steering systems installed in cars can generally be divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems.
