Installation Notes and Tips

Confirm the vehicle year and front position before installation. Compare the wheel pilot diameter, brake pilot diameter, hub pilot diameter, flange diameter, and 4-stud bolt pattern to the removed part to ensure correct match. Because this assembly includes an anti-lock brake sensor, inspect the connector and wiring path during service and clear any stored ABS codes after installation if required.
