Recognizing the signs of failing wheel bearings is vital for maintaining safety and performance. Common symptoms include:

  • Humming or growling noise that changes with speed
  • Vibration felt in the steering wheel or seat
  • Pulling to one side while driving
  • Uneven tire wear
  • Grinding noises when turning

These symptoms indicate that the wheel bearings may need inspection or replacement.
