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.

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.

Mercedes-Benz steering rack prices vary depending on the model, type of steering system, choice of original parts vs. replacements, etc. Typically, Mercedes-Benz steering rack prices range from $600 to $2,500, and additional expenses such as installation costs, other parts costs, and four-wheel alignment need to be considered during the replacement process.

Use a funnel to slowly pour the appropriate amount of power steering stop-leak fluid into the reservoir. Usually, the stop-leak fluid will start to work after mixing with the existing power steering fluid. Be careful not to pour too much stop-leak fluid to prevent the fluid level in the power steering rack from being too high.

Replacing the power steering rack is a technically demanding project involving multiple steps and details, requiring professional equipment and experienced technicians. The first step in replacing a power steering rack is to remove the steering system components. This includes removing the steering column, steering wheel, steering linkage, and power steering pump.

Continuously adding new fluid to delay repairs will cause car owners to ignore the seriousness of the problem. Once the hydraulic fluid in the power steering system is completely exhausted, the driver may suddenly lose steering assistance, especially when driving at low speeds, and the steering will become extremely heavy, making driving more difficult and dangerous.
