What to Do When the Steering Wheel of a Van Feels Heavy?
2 Answers
The heavy steering wheel of a van indicates an issue with the power steering system. The possible causes are as follows: 1. The power steering system contains a large amount of air, leading to abnormal steering. 2. Foreign objects in the steering hydraulic lines cause the steering pump flow control valve to stick. 3. Loose connections in the power steering system result in steering fluid leakage. 4. Excessive wear of the steering gear piston cylinder, poor oil seal sealing, or control valve sticking or damage. 5. The power steering warning light usually indicates heavy steering, steering noise, steering wheel vibration, or poor steering wheel return ability. Steering noise may occur due to the steering system operating under excessive load, causing excessive wear of the rotor and irregular movement of the oil in the pump, leading to noise. It could also be due to internal wear of gears and the rack-and-pinion steering gear assembly.
I've been driving a van for over ten years and have encountered heavy steering multiple times. The most common issue is with the power steering system, such as low power steering fluid level. Open the hood, locate the power steering fluid reservoir, and check if the fluid level is between MIN and MAX. If it's low, top it up with fresh fluid. Low tire pressure can also increase steering effort, so check the tire pressure immediately. The standard range is 30-35 PSI; inflate to the recommended level if it's low. If the problem persists, it might be due to a loose steering belt or a faulty power steering pump. Don't force it—heavy steering is dangerous and can lead to loss of control. Take it to a professional repair shop for inspection immediately. Regular fluid changes and steering system maintenance can help prevent this issue.
