NAF wheel bearings should last for about 100,000 to 150,000 miles, or approximately 5 to 8 years before they need to be replaced. However, the lifespan of wheel bearings can vary depending on various factors such as the quality of the bearings, driving conditions, and maintenance practices. It is important to have your wheel bearings inspected regularly by a qualified mechanic to ensure they are in good condition and to replace them when necessary.
