Full Answer

According to automotive experts, damaged wheel bearings must be changed immediately by a qualified mechanic to prevent accidents and damage to other components.

Aside from normal wear and tear, accumulated dirt inside the housing, overheating from lack of lubrication, and road bumps can cause a wheel bearing to fail prematurely.

Wheel bearings are made of hardened steel. They're designed to carry a car's weight and reduce rotational friction between the axle and the wheel to keep the vehicle moving smoothly. High-speed cornering and steep turns cause premature failure by generating excessive pressure on the bearings. Hitting curbs can also damage wheel bearings.

Unbalanced and out-of-round tires can quickly turn wheel bearings bad, reports AGCO Automotive Corporation. The continuous force exerted by defective tires causes damage to integral components of the suspension system, including tie rods, ball joints and struts.
