Step-by-Step Guide to Replace Wheel Bearing in Car
1. Remove the Wheel
Using a lug wrench, loosen the lug nuts on the affected wheel but do not remove them completely. Jack up the car and secure it with jack stands. Remove the lug nuts and pull off the wheel.
2. Remove the Brake Caliper
Locate the brake caliper and use a socket wrench to remove the bolts holding it in place. Carefully lift the caliper off the rotor without disconnecting the brake hose. Secure the caliper to the suspension using a bungee cord or zip tie.
3. Remove the Rotor
Remove the mounting bolts or screws holding the rotor in place. Gently tap the rotor with a hammer or mallet to loosen it. Slide the rotor off the hub.
4. Remove the Old Wheel Bearing
Inspect the hub for any damage or wear. Using a pry bar or flathead screwdriver, carefully pry the old wheel bearing out of the hub.
5. Clean the Hub and Bearing Seat
Thoroughly clean the hub and bearing seat using a wire brush or sandpaper to remove any dirt or debris. Apply a thin layer of sealant to the bearing seat.
6. Install the New Wheel Bearing
Lubricate the inner surface of the new wheel bearing with grease. Carefully insert the bearing into the hub and use a hammer or mallet to gently tap it into place.
7. Reinstall the Rotor
Slide the rotor back onto the hub and secure it with the mounting bolts or screws. Tighten them to the manufacturer’s specified torque.
8. Reinstall the Brake Caliper
Position the brake caliper back over the rotor and secure it with the bolts you removed earlier. Tighten the bolts to the appropriate torque.
9. Reinstall the Wheel
Place the wheel back on the hub and tighten the lug nuts by hand. Lower the car to the ground and use a lug wrench to fully tighten the lug nuts in a star pattern.
10. Test Drive and Inspect
Take the car for a test drive and listen for any unusual noises or vibrations. If everything seems normal, inspect the wheel bearing area for any leaks or loose connections.
Tips for Success
- Use quality parts and follow the manufacturer’s instructions carefully.
- Clean all surfaces thoroughly to prevent contamination.
- Lubricate the bearing properly to ensure smooth operation.
- Tighten all bolts and screws to the specified torque to prevent premature failure.
When to Replace Wheel Bearings
- Excessive noise or vibration during driving
- Loose or wobbly wheel
- Reduced fuel efficiency
- Uneven tire wear
- Visual inspection reveals damage or wear on the bearing
