What are the consequences of oil leakage from the car half-shaft oil seal?

[GraceFitz]

Oil leakage from the car half-shaft oil seal can result in the following consequences: 1. A reduction in the amount of lubricating oil in the drive axle, affecting normal lubrication and accelerating wear and tear on mechanical components, leading to premature damage; 2. The lubricating oil may flow into the wheel-side reducer, causing an increase in the oil level of the wheel-side reducer, which can damage the oil seal and leak into the brake drum, resulting in poor braking performance and posing a safety hazard. An oil seal is a type of sealing component used to contain grease in mechanical parts, primarily preventing the leakage or seepage of lubricating oil or grease. The half-shaft oil seal specifically prevents the leakage or seepage of lubricating oil or grease from the half-shaft, isolating the lubricated components in the transmission system from the output components to prevent oil leakage.
