• Use a hammer and a socket to gently tap the bearing into place.

7. Install the Hub

• Place the hub onto the spindle and secure it with the hub nut.
• Tighten the hub nut to the specified torque using a torque wrench.

8. Install the Rotor

• Slide the rotor onto the hub.
• Use a hammer to gently tap the rotor into place.

9. Install the Brake Caliper

• Reattach the brake caliper to the hub and tighten the mounting bolts.
• Torque the bolts to the specified torque using a torque wrench.

10. Install the Wheel

• Place the wheel onto the hub and tighten the lug nuts.
• Lower the vehicle and fully tighten the lug nuts using a torque wrench.

11. Test Drive

• Start the vehicle and take it for a short test drive.
• Listen for any unusual noises or vibrations.
• Check the wheel bearing temperature after driving a few miles. It should not be excessively hot.

Troubleshooting

• If you encounter any difficulties during the process, consult a qualified mechanic.
• If the new wheel bearing fails prematurely, it may indicate an underlying issue with the spindle or other components.
• Always refer to the Mazda 6 service manual for specific torque specifications and additional instructions.
