- Rotational Support: The inner ring mounts on the spindle, the outer ring in the hub bore, with rollers rolling between them for smooth wheel rotation.
- Load Bearing: Tapered roller bearings simultaneously handle radial loads (vehicle weight and payload) and axial loads (cornering lateral forces, acceleration/braking longitudinal forces).
- Friction Reduction: Rolling contact replaces sliding contact, significantly reducing friction, energy loss, and heat generation.
- Precise Positioning: Ensures accurate wheel-to-spindle alignment for proper wheel alignment parameters, driving stability, and even tire wear.
| Symptom | Probable Cause |
|---|---|
| "Humming" or "howling" noise from front wheels, varying with speed | Worn bearing races or rolling elements; fatigue spalling |
| Front wheel wobble or vibration; steering wheel shake | Excessive bearing clearance or worn rollers |
| Abnormal hub overheating | Excessive bearing preload or lubrication failure |
| Uneven tire wear (excessive inner or outer edge wear) | Worn bearing causing wheel misalignment |
| "Clunking" metallic noise when cornering | Severely worn bearing or damaged cage |
- Verify part number on original part before ordering
- Replace in pairs (left and right) for consistent performance
- Follow ISUZU factory workshop manual specifications for preload torque
- Use high-quality wheel bearing grease during installation
