For novices, one of the most important challenges is the lack of practical operating experience. Replacing the power steering rack and pinion is a delicate job, and any operational error can cause the entire system to operate abnormally.

When the power steering pump fails, the driver usually feels that the steering wheel becomes heavier, but there is no obvious jamming feeling. When the power steering rack fails, the driver may feel a change in the resistance to steering wheel turning, especially jamming at certain angles.

Because the manual steering system is usually designed to be simple, and in some models, the design of the wheel and steering system does not take into account too much power assistance, the manual steering rack needs to bear greater pressure.

The ECU is the control center of the entire electric power steering system. If the ECU is suspected to be faulty, the fault code can be read through the vehicle diagnostic system. Modern cars are usually equipped with an on-board diagnostic system (OBD-II) that can help technicians quickly identify problems in the ECU.

The size of the leak is a key factor in determining the rate of leakage. If the leak is large, such as a completely broken seal or cracked high-pressure pipe, the power steering fluid may leak a large amount in a short period of time. In this case, the driver will quickly notice that the steering has become unusually heavy and the vehicle's power steering function is almost ineffective.

Bent or damaged rack and pinion steering will cause it to no longer cooperate accurately with other components. At this time, the steering system will become heavy or slow to respond, and the driver will need to exert more force to turn the steering wheel.

As the world's first internal combustion engine car, the steering design of the Benz patented car was very simple. Since the Benz patented car was a three-wheeled vehicle, it did not have the complex steering system we know today.

The electric power steering gear does not need to use steering oil. The electric power steering gear is completely powered by electronic components and electric motors, and no longer relies on hydraulic pumps and hydraulic pipelines, so it does not require hydraulic oil for lubrication or power.

For leaks at the hose or accessories, replacing the damaged hose or accessories is the best way to stop the leak. Aging or damage to the hose is one of the main causes of power steering pump leakage, so it is very important to check the condition of the hose regularly and replace it in time.

Abnormal The driver will feel that the steering wheel becomes unusually heavy, especially at low speeds or when parking. This situation not only makes driving more difficult, but also increases the danger of driving, especially in emergency situations.
