The performance of a repaired power steering rack depends on the quality of the repair and the severity of the problem. In some cases, the repair may not fully restore the original performance of the rack, especially when the internal mechanical parts are already severely worn.

In the current automotive market, hydraulic power steering systems (HPS) and electronic hydraulic power steering systems (EHPS) are still widely used, and both systems rely on power steering pumps.

HPS racks are more common in large vehicles and some high-performance models that focus on driving experience. These types of vehicles have high requirements for the durability, reliability and steering feel of the steering system, and the HPS system has obvious advantages in this regard.

The power steering rack is connected to the steering gear and steering wheel, and is responsible for converting the driver's steering instructions into actual steering actions of the wheels. Traditional mechanical steering requires a lot of force, while the power steering makes steering easier.

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.
