Professional mechanic or driveline specialist installation is strongly recommended.

1. Ensure vehicle is safely raised — Use appropriate jack stands or a lift to support the axle.
2. Remove the wheel and hub assembly — Access the bearing for replacement.
3. Remove the old bearing cone — Use a proper bearing puller or press. Do not hammer directly on the bearing.
4. Clean and inspect — Clean the spindle and hub bore. Check for wear, scoring, or damage.
5. Install the new bearing cone — Press the cone evenly onto the spindle using a proper driver. Ensure it seats fully against the shoulder.
6. Lubricate — Apply the specified wheel bearing grease or gear oil to the bearing.
7. Install the matching cup — Press the new cup (HH506310 or HH506311) into the hub bore.
8. Adjust bearing preload/endplay — Set to manufacturer specifications using a dial indicator or torque wrench.
9. Reassemble hub and wheel — Torque all fasteners to specification.
10. Road test — Test drive to verify smooth operation and no abnormal noise or vibration.
