Can you drive with a broken wheel hub?
If your wheel hubs are beginning to show signs of wear to the bearings - the “growling” noise is not very pronounced - you may yet have some life left in them. Make sure to pay attention, though, because severely worn or damaged wheel hubs and bearings can become dangerous.
What happens when a wheel hub goes out?
Slightly worn wheel hubs and bearings may be a slight nuisance because of the sound they make. Significantly worn or damaged bearings, on the other hand, can cause a wheel to lock up or fall off while driving.
Should I replace my wheel hub or just the bearing?
Whether or not the wheel hub and bearing can be replaced independently of one another really depends on your vehicle make and model. Some wheel hubs are fitted with tapered bearing sets that can be removed and replaced. Others have sealed bearings that must be pressed into the hubs. Still, others require that both the hub and bearings be replaced as an assembly.
