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.

Hydraulic power steering system is one of the earliest technologies to replace traditional rack and pinion steering systems. The system greatly reduces the force required by the driver to turn the steering wheel through the pressure provided by the hydraulic pump, thereby improving the comfort of control.

Here are some of the most common symptoms: 1. Steering wheel shakes or loosens 2. Steering is not sensitive 3. Abnormal noise 4. Steering wheel is difficult to return automatically 5. Steering accuracy decreases 6. Steering system leakage 7. Steering wheel vibration 8. Uneven tire wear

The cost of replacing a Mercedes-Benz steering rack varies depending on the model, part type, labor cost and other factors. For entry-level models such as the C-Class, the cost may be between $1,200 and $2,500, while for premium models such as the S-Class, the cost may be as high as $4,000 or even more.
