Axles and shafts transfer rotational power from the transmission and differential to the wheels, enabling vehicle movement. These components are integral to the drivetrain, located within the wheel hubs and spanning between the differential and wheel assemblies. Axle types include full, stub, and float, differing in load-carrying capacity and mounting configuration. Shafts, often splined for connection, transmit torque while accommodating suspension and steering articulation. Key features include varying diameters, spline counts, and material compositions optimized for specific vehicle weights and performance characteristics. Consistent adherence to dimensional tolerances and material specifications is critical for driveline efficiency and longevity.
