The wheel bearing’s two primary functions include ensuring the wheel rolls along the road and supporting the weight of the vehicle. If you’re lucky, wheel bearings can last up to 150,000 miles. However, once your car has over 75,000 miles, the wheel bearings could start acting up at any time.The hub that encapsulates and carries the bearing is connected to the spindle, which is attached to the rest of your car’s suspension. You may notice a hissing, grinding, or “whirring” noise before the bearing fails. If this happens, don’t delay repairs—when the wheel bearings “go” they may take other parts out with them.
The most noticeable sign of a busted wheel bearing is a violent shake or “death wobble” that gets worse and worse the faster you go. Do not attempt to drive your car if this symptom appears, as it can be quite dangerous.
