　　Power steering systems are essential for smooth and effortless vehicle maneuverability. However, like any mechanical component, power steering systems are prone to issues, with oil seal leaks being a common concern. In this article, we will explore the most prevalent cause of power steering oil seal leaks, providing valuable insights into the root cause and offering practical advice for prevention and resolution.

　　The Leading Cause: Seal Degradation and Wear

　　The most common cause of power steering oil seal leaks can be attributed to the degradation and wear of the seals within the system. These seals, typically made of rubber or elastomer materials, play a critical role in maintaining a tight seal and preventing oil leakage.

　　Over time, exposure to high temperatures, hydraulic pressure, and contaminants can lead to the deterioration of the seals. The continuous movement and stress placed on the seals during steering maneuvers further contribute to their wear and eventual failure, resulting in oil leakage.

　　Common Points of Leakage:

　　Pump Seal: The power steering pump is a primary area where oil seal leaks occur. The pump seal, located between the pump housing and the rotating shaft, is responsible for maintaining a seal to prevent oil leakage. As the pump operates, the seal may wear out or develop cracks, leading to oil seepage and visible leaks around the pump.

　　Rack and Pinion Seals: In vehicles equipped with a rack and pinion steering system, the seals within the steering rack are susceptible to leakage. These seals, located at both ends of the rack, are responsible for preventing oil from escaping. Factors such as age, prolonged use, and exposure to harsh conditions can cause the seals to degrade and result in oil leaks.

　　Prevention and Resolution:

　　Regular Maintenance: Implementing a routine maintenance schedule for the power steering system is crucial to identify potential issues before they escalate. Regularly inspecting for
