When wheel bearings fail, they can contaminate the grease in the spindle assembly. This contaminated grease can then cause premature wear on the spindle, leading to several issues.
- Excessive play: The spindle can develop excessive play, allowing the wheel to wobble and causing the vehicle to vibrate.
- Damage to the bearing races: The bearing races on the spindle can become damaged, causing the bearings to fail prematurely.
- Spindle failure: In extreme cases, the spindle can fail, causing the wheel to come loose from the vehicle.
