Unlike other car parts, wheel bearings are not designed to wear out at specific, regularly timed intervals. Instead, these bearings are damaged over time. This can happen if you get into an accident or hit a curb or pothole. Sometimes mud, road salt, sand or water can get inside the seal and affect the grease in the wheel bearing. This can cause issues that will require a repair or a new set of wheel bearings.
If you have wider or larger tires than normal, you may need to replace your wheel bearings more often than if you had original equipment manufacturer (OEM) specific tires. In general, wheel bearings can last up to 150,000 miles, but this depends on how you drive. For example, if you get into a car accident, your wheel bearings may be damaged.
