Tools and Materials Needed:
- Jack and jack stands
- Lug wrench
- Socket wrench
- Flat-head screwdriver
- Ball joint separator (optional)
- Hammer (optional)
- Replacement bearing assembly (pre-greased)
Instructions:
1. Safety First:
- Engage the parking brake and chock the rear wheels to prevent the vehicle from rolling.
- Loosen the lug nuts on the front passenger wheel, but don't remove them completely.
2. Raise the Vehicle:
- Use the jack to safely lift the front of the vehicle until the front passenger wheel is about 6-8 inches off the ground.
- Securely place jack stands under the designated areas to support the vehicle.
3. Remove the Wheel:
- With the wheel slightly off the ground, remove the lug nuts completely and take off the wheel.
4. Locate the Axle Nut:
- Inside the wheel hub, find the axle nut. This nut is usually large and might have a cover. Remove the cover, if present.
5. Remove the Brake Caliper:
- Unbolt the brake caliper from the mounting bracket. Be careful not to strain or damage the brake line.
- Use a piece of wire or twine to hang the caliper out of the way without letting it hang freely from the brake hose.
6. Remove the Rotor:
- Take off the lug nut(s) securing the rotor to the wheel hub. Remove the rotor by carefully wiggling it off.
7. Remove the Ball Joint (if required):
- Depending on the vehicle, you may need to detach the ball joint from the lower control arm. This can be done using a ball joint separator or by carefully prying it apart with a flat-head screwdriver and a hammer.
8. Expose the Wheel Bearing:
- Remove any splash shields or covers around the wheel bearing assembly to expose it completely.
9. Remove the Bearing Assembly:
- Use the appropriate socket wrench to loosen and remove the bolts holding the bearing assembly in place.
- Gently pry out the bearing assembly from its housing. Be cautious not to damage the bearing or surrounding areas.
10. Install the New Bearing:
- Insert the new bearing assembly into the wheel hub. Make sure it seats properly.
- Secure the bearing assembly using the provided bolts. Tighten the bolts to the recommended torque specifications (refer to your vehicle's repair manual).
11. Reconnect Components:
- Reinstall any components you removed earlier, including the ball joint (if applicable), rotor, brake caliper, and wheel.
12. Lower the Vehicle:
- Once everything is securely in place, carefully lower the vehicle using the jack and jack stands.
13. Test Drive:
- After replacing the wheel bearing, take the vehicle for a short test drive to ensure that the wheel rotates smoothly and there are no unusual sounds.
14. Retighten Bolts (after test drive):
- After the test drive, re-check and retighten the bolts securing the wheel bearing assembly to the wheel hub.
Remember, if you're not confident in your ability to perform this repair or encounter any difficulties, it's best to consult a professional mechanic to avoid potential safety risks.
