Installation Notes and Tips

Confirm rear-position fitment before ordering and verify the spline count, bolt circle diameter, and pilot dimensions against the original part. Because the anti-lock brake sensor is not included, reuse or source the vehicle’s existing ABS-related components as required by the application. Always inspect the mating surfaces, axle interface, and fasteners during installation, and torque all hardware to the vehicle manufacturer’s specifications.
