Installation Notes

Confirm rear fitment by matching the vehicle year, Saab 9-3 model, and part number WA512307 before installation. Inspect the axle flange, mounting surface, and brake components for wear or damage during service. Because this assembly includes the ABS sensor, verify connector routing and sensor alignment during installation to maintain proper brake system operation.
