Installation Notes and Tips

Confirm rear fitment by year, make, model, and standard grade application before installation. Verify spline count, bolt circle, pilot diameters, and flange offset against the original part to ensure correct replacement. Because the ABS sensor is not included, reuse or transfer the vehicle’s existing sensor setup if required by the application. Always inspect related components such as the axle, brake rotor, and mounting surfaces during service.
