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.

Advantages of hydraulic power steering system: Provides stable and powerful steering assistance Sensitive feedback and precise control Strong adaptability, suitable for a variety of vehicles High stability and reliability Relatively low cost Disadvantages of hydraulic power steering system: Low fuel efficiency Large volume and increased weight Complex maintenance and many vulnerable parts Inferior control feel to mechanical steering High noise

Hydraulic power steering racks can significantly improve the controllability of trucks and reduce the labor intensity of drivers. For large trucks that are driven for a long time, hydraulic power steering racks make it easier to operate the steering wheel and avoid fatigue caused by long-term steering burdens.

The operation between the rack and the pinion depends on adequate lubrication. When the power steering fluid is exhausted, this lubrication function fails, resulting in excessive friction between metal parts and abnormal wear. The gear portion of the rack will be damaged due to direct contact, and eventually the steering rack will fail.

Mineral oil hydraulic oil is the most common type of hydraulic oil, which is mainly processed from oil-based oil products extracted from crude oil. They usually contain additives to enhance the anti-oxidation, anti-corrosion, anti-foaming and other properties of hydraulic oil.

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.
