Frequently asked questions
- humming noise from wheel that gets louder with speed?
- A drone that rises with road speed and changes when you steer is a wheel bearing. If it stays identical while steering, look at tyres.
- Is it safe to drive with this?
- Short local trips are usually fine, but the fault will get worse and often damages other parts if you leave it.
- How much does it cost to fix?
- The most likely repair is wheel bearing replacement, which runs $155–$875 in the US including labour, or $60–$380 in parts if you fit it yourself.
