Tire Talk - Handling the Load Wheel Bearing Diagnosis
Although wheel bearings are often the most neglected part of the vehicle, they nevertheless have a critical job to do, and in most cases, do it very well. Not only are wheel bearings designed to support the weight of the vehicle and allow it to travel over a road with a minimum of rolling friction, the bearings must also withstand the thrust loads generated by high-speed cornering and hard acceleration and braking. In addition, most wheel bearings must operate in a hostile environment ranging from 40 F on a cold start-up to more than 400 F during heavy braking. Worse still, the muddy, silt-laden water of Americas southern flood plains have recently ruined thousands of wheel bearings by contaminating them with dirt and water. Its All Ball Bearings Nowadays Ball-type wheel bearings were very popular on early vehicles because they were easy to manufacture and install. Moreover, since ball-type wheel bearings have minimal load-bearing area between the ball and the inner and outer bearing races, their rolling friction is usually low. On the other hand, this lack of load-bearing area makes adjustment and lubrication critical because a combination of too much preload and incorrect bearing grease will cause rapid failure.  Rolling in the 50s During the late 1950s, tapered roller wheel bearings became popular because the larger contact area between the roller and bearing races increased their load-bearing capacity and made them more reliable.
