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 your vehicle is equipped with a hydraulic power steering system, first check the level of the steering hydraulic fluid. If the level is too low, there may be an oil leak, which is usually one of the signs of a damaged steering rack gear.

When the power steering system fails, the driver needs to rely on more manual force to turn the steering wheel, especially when driving at low speeds or parking. Without power assistance, the steering wheel becomes extremely heavy to turn, which is a big challenge for some drivers with less power.

When the hydraulic power steering rack becomes loose, the response of the steering wheel may become sluggish. When the driver turns the steering wheel, he does not feel the immediate response that should have been there, but needs to spend more force or time to complete the steering operation.

Power steering leak stopper is a common commercial product that usually fills the leak point by adding a chemical to the power steering fluid, especially the aging or cracks of the seal. Leak-stopping agents work by forming a hardened film of chemicals at the leak point through contact with air or temperature, sealing the leaking fluid and slowing or stopping the leak.

Benefits of replacing a new power steering rack: 1. Restore the performance of the steering system 2. Improve driving safety 3. Extend the service life of the vehicle 4. Improve the driving experience 5. Economic and environmental benefits

Through the above analysis, it can be concluded that not all steering racks require hydraulic oil. Specifically, the steering racks of manual steering systems and electric power steering systems do not require hydraulic oil, while the steering racks of hydraulic power steering systems rely on hydraulic oil to provide steering assistance.
