The care and maintenance of the steering wheel infrequently, or late maintenance is the leading cause of the heavy steering wheel, difficult to drive. When encountering this problem, we need to check the power steering oil and power pump first, and then check for other problems.
Due to tire pressure
Poor tire pressure can cause heavy steering, especially a flat tire, all tires must be inflated to the manufacturer's recommended PSI. In addition, if the front tires are worn unevenly or do not rotate regularly, this problem can also be caused.
Inefficient steering wheel
The steering wheel is linked to the steering wheel through the shafts and U-joints, driving every day causes these parts to wear out, if the steering wheel is hard right after starting, the cause is definitely from the ruler. drive. After that, the steering wheel will gradually regain a smooth feel, this is because when the engine starts, the steering wheel will be better lubricated. You can continue to drive in this condition, but too long will damage the steering wheel.
Power booster pump drive belt is loose
Another common cause of hard steering is a loose power-pump drive line, which causes a lack of drive power.
Power steering oil missing or leaking
Missing or leaking steering oil is the leading cause of steering wheel difficulty turning will lead to lack of pressure in the pump leading to the steering wheel not being supplied with enough oil to help the steering wheel rotate easily.
Power booster pump
Along with the fluid, the power steering pump has the main role to create enough pressure for the power steering system, if the pump fails or stops working for any reason, it will be very difficult to steer. In this case, the cause may be due to worn power steering pump impeller, open oil line to the steering wheel or scratched pump surface. If the power steering pump fails, the steering wheel will come to a complete stop.
Power steering oil is dirty, concentrated
Like all vehicle fluids, power steering fluid also accumulates dirt and debris over time, and when it becomes too thick, or too dusty, to lubricate. steering shaft.
The reason why the steering wheel is slow
This phenomenon is usually caused by the inefficient power steering pump, which will cause the pressure and oil flow through the pump to decrease, causing the steering wheel to move slowly when steering, if the steering wheel is open, the oil will leak through and also cause the steering wheel. delayed payment. In addition, lack of power steering oil or poor tire pressure also causes this phenomenon.
