What It Helps Address

• Wheel looseness or play caused by hub wear
• Uneven wheel mounting from damaged flange or pilot surfaces
• Vibration or roughness traced to rear hub deterioration

Installation Notes and Tips

Confirm rear-position fitment before installation and verify the vehicle is a 2014-2018 Mazda 3 or Mazda 3 Sport Standard Grade application. Compare the flange, pilot, stud, and bolt-circle dimensions to the removed part before pressing or bolting the assembly into place. Because the ABS sensor is included, inspect the connector routing and tone/sensor interface during installation to help avoid warning lights after service.
