As wheel bearings wear down, they can produce telltale signs that you shouldnt ignore:
* A grinding or humming noise while driving, which intensifies with speed
* Vibration or shaking in the steering wheel or vehicle
* Increased play or looseness in the wheel when turning
* Uneven or scalloped tire wear on one specific tire
Causes of G35 Wheel Bearing Failure
Various factors can contribute to wheel bearing failure in your G35:
* **Improper installation or maintenance:** Insufficient lubrication or improper torque can shorten lifespan.
* **Excessive weight or load:** Overloading your G35 puts extra stress on bearings.
