Wheel bearing is a component of truck drivetrain. It ensures mechanical connection, alignment and free rotation of the wheel hub on the axle.

In addition to the component itself, wheel bearing kit may include races, seals, retaining rings, protective caps, plugs, gaskets, pins, cotter pins, bolts, nuts, etc.

When it is time to install the kit

The components are highly reliable, but they fail over time due to mechanical load. Both ball and roller wheel bearings in cars, and tapered ones in trucks need replacing due to natural abrasion of metal, or appearance of defects on the race.
