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 it is only a small leak, the vehicle can still be driven for a short distance, but it needs to be checked and the hydraulic oil added frequently. However, if the oil leak is serious and the hydraulic oil is lost quickly, the vehicle may lose the power-assist function in a short time, and continuing to drive at this time will bring great risks.

The cost of replacing the steering rack varies depending on the model. For Mercedes-Benz models, the cost of replacing the steering rack is generally between $1,000 and $2,500. This cost includes the cost of parts and labor.

The work of the electric power steering system begins with the steering force sensor (Torque Sensor). When the driver turns the steering wheel, the sensor monitors the rotational torque on the steering wheel in real time. This information is transmitted to the vehicle's electronic control unit (ECU), and the ECU determines how much steering assistance is needed based on this information.

Steps for calibrating the power steering rack 1. Lift the front of the vehicle 2. Loosen the steering rack connection components 3. Adjust the steering wheel position 4. Measure and adjust the rack position 5. Tighten the rack connection components 6. Check and calibrate the steering wheel position 7. Test the steering system

"Do I need to align the steering rack and tie rod after replacing it?" The answer is yes, in other words, after replacing these parts, the geometric relationship between the vehicle's tires, suspension system and steering system must be recalibrated to ensure the safety, stability and driving experience of the vehicle.

The hydraulic power steering rack and the four-wheel alignment seem to be two independent systems, but their working conditions are closely related. Although the hydraulic power steering rack mainly affects the steering ability of the vehicle, its good or bad condition will also indirectly affect the performance of the four-wheel alignment.
