Installation Notes and Tips

Verify front fitment by year, make, and model before installation. Confirm the hub uses a 3-bolt flange pattern, 6 wheel studs, and the listed dimensions of 37.5 mm inside diameter and 91.25 mm outside diameter. The ABS sensor is not included, so reuse or source the sensor separately if your vehicle requires one. Always inspect the mating surfaces, torque fasteners to factory specifications, and check wheel bearing preload and axle/hub seating during installation.
