When the rear outer hub oil seal exhibits the following conditions, timely inspection and replacement are required:
- Visible oil stains around rear hub: Aged or worn seal lip causing lubricant seepage from outer hub, oil contamination visible on hub surface and tire inner sidewall.
- Rear wheel bearing noise or overheating: Seal failure causing grease loss, bearing lacking lubrication, humming or grinding noise from rear wheel during driving, abnormal hub temperature rise.
- Brake drum or disc contaminated with oil: Lubricant leakage from seal contaminating brake components, causing reduced braking performance and brake pull.
- Increased hub bearing play: Long-term lack of lubrication causing accelerated bearing wear, abnormal hub wobble affecting driving safety.
- ABS sensor fault (if equipped): Lubricant leakage from seal contaminating ABS sensor, triggering ABS warning light.
