A torque hub is a compact, wheel-end drive assembly that transmits power from the drive motor to the wheel, providing the tractive effort the machine needs to travel across a job site. The bearings inside the hub support the rotating shaft and planet gear carrier under the combined load of the machine's weight and drive forces — when they wear or fail, the hub develops play, generates noise, and loses efficiency, which can affect drive responsiveness and accelerate damage to surrounding components. Replacing the bearings using the correct kit for torque hub 45553GT restores the hub's structural integrity and keeps the drive unit functioning as designed.
