A bearing lets a rotating shaft or hub turn with low friction while holding it in position. A worn bearing in the differential, transfer case, or wheel hub can make a growling, humming, or grinding noise that changes with vehicle speed, or it can develop noticeable play. These symptoms can have other causes, so diagnose the source before replacing the bearing. Follow the vehicle service information for the correct installation procedure.
