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.

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.

Damage to the power steering rack may affect the flow of power steering fluid. Under normal circumstances, the fluid circulates in the system to play a lubricating and cooling role. If the power steering rack is damaged, the fluid may not flow properly, causing localized temperature increases.

The wear of the rack may cause the meshing between the rack and the pinion to no longer be smooth, or even gaps or abnormal contact. Especially when driving on bumpy roads, the vibration of the vehicle will aggravate this wear, causing the power steering rack to make a "clicking" sound.

The work of the steering rack and pinion involves a lot of friction and mechanical stress. If these metal parts are not adequately lubricated after long-term use or dry-grip due to lack of power steering fluid, they will gradually wear or produce gaps. These wears will destroy the sealing of the rack system and allow hydraulic oil to leak from these gaps.

Normally, the rack of the power steering rack should not move excessively. The purpose of the rack design is to fix the steering rack so that it can move smoothly during the steering operation and provide assistance to the driver through a hydraulic or electric power system.

After turning off the power, it is recommended to wait a few minutes to ensure that the electric steering system is completely powered off. This step is critical to the smooth progress of the reset process and ensure that the electronic control unit (ECU) inside the system no longer retains any cache or error codes.

If the noise comes from the front of the vehicle, especially near the wheel or chassis, and is accompanied by hydraulic hum, gear jamming, or hydraulic oil leakage, the problem is most likely with the power steering rack or power steering system.

Steering power reduction or failure When the hydraulic oil deteriorates, the viscosity increases and the fluidity deteriorates, which will cause the working efficiency of the hydraulic pump to decrease, thereby weakening the hydraulic steering rack power.
