A car’s wheels rotate on tapered-roller bearings which fit between the stationary axle spindle and the rotating wheel’s hub/brake mechanism. There are bearings on the inner and outer side of the hub to properly support the wheel. These are greased when installed, but the grease can, and does, break down over time, allowing dry contact between the various elements. When left unattended, this will lead to wear and, ultimately, to bearing failure.
Consider having this job done when your vehicle reaches high mileage, particularly if it has been operated with heavy loads or on unusually bumpy roads.
A catastrophic wheel bearing failure can lead to the wheel coming off the car. Obviously, that could cause an accident or, at the very least, serious damage to the vehicle. It’s certainly worth discussing with one of our mechanics.
Tell us what the problem is (e.g the car is not starting or I need new shock absorbers). What kind of car you drive and your contact information.
