What goes wrong
The wheel bearing is a crucial component that allows your wheels to spin freely. Over time, the internal lubrication can break down, leading to excessive friction, heat, and eventually failure of the bearing unit. This can manifest as a grinding or humming noise that worsens with speed or when turning.
Symptoms to watch for
- Grinding, humming, or roaring noise from a wheel that changes with speed or when turning
- Vibration felt through the steering wheel or floorboards
- Loose or wobbly wheel when jacked up
- Uneven tire wear
- ABS or traction control warning lights (in severe cases)
Root cause
Premature wear due to manufacturing defects in some early models, or simply extended exposure to road grime, water, and road salt which degrades the bearing's internal seals and grease.
Buy time with these
- • Regular inspection of wheels for excessive play
- • Avoiding driving through deep puddles or floodwaters
- • Prompt replacement at the first sign of noise or vibration
Permanent fix
- Replacement of the failed wheel bearing hub assembly.
- Inspect surrounding components like axles and brake components for any related damage.
