Generally speaking, car wheel hub bearings will be replaced and inspected at 50,000 kilometers under normal circumstances, and about 100,000 kilometers. But this answer cannot be generalized. The life cycle of automobile wheel bearings is also related to road conditions and personal driving habits. Car wheel bearings are part of the transmission system.
Improperly installing the wrong tool, such as a hammer or impact wrench, can damage the interior and/or interior of the wheel end bearing, causing premature wheel bearing failure. In addition, instead of replacing new parts, old accessories such as bolts, nuts, snap rings, cotter pins, and sealing rings can be reused.
Poor quality wheel bearings, wheel bearings are subject to a lot of stress. Wheel bearings made from inferior materials are improperly heat treated, causing early wear and failure. Depending on driving conditions, driving in deep water or mud can cause wheel bearing failure.
Water, mud or other contaminants (such as dust or road salt) enter the bearing through the seal, contaminating the grease and wearing out the bearing. After car modifications, larger or wider rims, tires with low thread ratios, harder shock absorbers, and suspension springs will cause higher loads on the wheel bearings and accelerate wear.
Adhere wheels, tires, shock absorbers and springs according to the vehicle manufacturer's specifications to minimize the impact on wheel bearing life. The bearings are used normally without external impact and almost do not need to be replaced. So far, the most used bearings have exceeded 500,000 kilometers and are still in use.
Most of the causes of bearing damage are caused by external collisions! Bearings can easily be damaged by hitting a curb, squatting on a tire on a rough road, etc.! Today, most trucks still use older tapered needle bearings. This kind of bearing has a simple structure but requires regular maintenance.
