This tapered roller bearing supports radial and axial loads in the gearbox or wheel hub of the host vehicle. It consists of an inner ring, outer ring, and tapered rollers that roll between the two raceways, allowing the assembly to handle combined loads in one direction. A worn bearing produces audible rumble and increased free play in the rotating assembly, which can lead to misalignment of the driven components. The manufacturer's original geometry matches the housing and shaft shoulder heights of the original assembly, so no additional shimming is required during installation. On reinstall, ensure the bearing is pressed squarely onto the shaft and that the retaining nut is torqued to the specified value.
