About this part
Wheel bearings on your H3 GMT345 let the wheels spin freely with minimal friction. A failing bearing creates a distinctive humming or growling noise that worsens with speed and requires prompt replacement.
Frequently asked questions
How do I know which wheel bearing on the Hummer H3 needs replacing?
On your H3 GMT345, the noise typically gets louder when turning in one direction – a bad left bearing is louder turning right (weight shifts left) and vice versa.
Should I replace wheel bearings in pairs?
It's not strictly necessary, but if one side has failed, the other may be close behind. Replacing both on the same axle is a common preventive choice.
