Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. Verify the flange bolt hole pattern and stud size (M12 x 1.5) match the vehicle specifications. Since the assembly includes the ABS sensor, carefully connect the sensor wiring without damage. Do not attempt to grease the bearing as it is a sealed unit. Proper torque specifications should be followed for flange bolts and wheel studs to ensure safe operation.
