Wheel Bearing Failure and Replacement
A wheel bearing consisst of small steel balls or rollers that support the wheel and allow it to spin freely. Located at the center of the wheel inside the hub, they reduce friction by letting the hub roll around the axle.
Proper lubrication and regular check-ups help the bearings run smoothly. If you hear unusual noises like clicks, rumbles, or groans that change with speed, the bearings might be worn or damaged. In that case, an inspection is necessary.
Ask your service advisor to check your wheel bearings if your brake pads take longer than usual to engage or if you hear grinding noises while driving. Damaged bearings can generate excessive heat, causing the wheel to lock up. Any damage prevents the wheel from rotating smoothly.
If you don’t replace bad wheel bearings in time, a locked wheel can come off, causing significant damage. From a safety perspective, this presents a major risk, as a wheel detaching can lead to accidents. Environmentally, failing components like this have little impact.
Wheel Bearing Service
Most modern cars use sealed bearings that you cannot service. Don’t let anyone sell you something you don’t need. If wear-related issues arise, simply replace the bearing to avoid serious situations that could leave you stranded.
