Installation Notes

Verify rear-position fitment before ordering and confirm the wheel stud count, bolt circle, and pilot diameters against the original part. Because the ABS sensor is included, inspect the connector and wiring during installation to ensure proper system operation. Always torque fasteners to the vehicle manufacturer’s specifications and check wheel bearing preload and hub seating after installation.
