Why is my electric power steering stiff when I turn?
If you're experiencing stiff or heavy steering when turning your vehicle, it could be due to an issue with your electric power steering system. Electric power steering (EPS) systems use an electric motor to assist the driver's steering input, making it easier to turn the wheels. However, when the system is not functioning properly, it can result in a stiff or heavy steering feel.
Potential Causes of Stiff Electric Power Steering
There are several potential reasons why your electric power steering may feel stiff when turning the wheel:
- Low power steering fluid level: The EPS system relies on a specific type of power steering fluid to lubricate and cool the electric motor. If the fluid level is low, it can cause the system to operate less efficiently, leading to a stiff steering feel.
- Faulty power steering motor: The electric motor that provides the power steering assist can fail over time, causing the steering to feel heavy and unresponsive. This may be due to wear and tear, electrical issues, or a problem with the motor itself.
- Steering rack or linkage issues: Problems with the steering rack, tie rods, or other linkage components can also contribute to a stiff steering feel, as these parts are responsible for translating the driver's input into wheel movement.
- Sensor or wiring problems: The EPS system relies on various sensors and wiring to monitor the steering input and provide the appropriate amount of assist. If these components are malfunctioning, it can result in a stiff or unresponsive steering feel.
If you're experiencing stiff or heavy steering, it's important to have your vehicle inspected by a qualified mechanic to diagnose and address the underlying issue. Ignoring the problem can lead to further damage and potentially unsafe driving conditions.
