Without bearings, the vehicle's parts would quickly wear out from friction. Typically, bearings in a vehicle have to deal with radial and thrust loading. Radial load makes the bearing rotate or roll as a result of tension. Thrust load, or axial load, is associated with the bearing's carrying capacity and is applied parallel to the bearing's axis. When it comes to the vehicle, its weight carry a radial load, however, when it goes around a turn, the bearings deal with a thrust load from the cornering forces.
