- Engage the parking brake.
- Place wheel chocks behind the wheels opposite the one being worked on.
Step-by-Step Repair Guide
1. Remove the Wheel
Using a lug wrench, loosen the lug nuts on the affected wheel but do not remove them completely. Place the floor jack under the designated jack point and raise the vehicle until the wheel is slightly off the ground. Remove the lug nuts and carefully remove the wheel.
2. Remove the Brake Caliper
Locate the brake caliper bolts and remove them. Carefully lift the caliper off the rotor and suspend it with a bungee cord or wire to avoid damaging the brake line.
3. Remove the Rotor
Using a socket wrench, remove the rotor bolts and gently tap the rotor with a hammer to loosen it. Slide the rotor off the hub.
4. Remove the Hub Assembly
Locate the hub assembly bolts and remove them. Carefully pull the hub assembly straight out of the wheel bearing.
5. Remove the Old Wheel Bearing
Using a punch and hammer, carefully drive out the old wheel bearing from the hub assembly. Be cautious not to damage the hub.
6. Install the New Wheel Bearing
Apply a thin layer of grease to the inner and outer races of the new wheel bearing. Carefully press the new bearing into the hub assembly using a socket and hammer.
7. Reinstall the Hub Assembly
Place the hub assembly back into the wheel bearing. Align the bolts and tighten them to the specified torque.
8. Reinstall the Rotor
Slide the rotor onto the hub assembly and tighten the rotor bolts to the specified torque.
9. Reinstall the Brake Caliper
Lift the brake caliper back onto the rotor and tighten the caliper bolts to the specified torque.
10. Reinstall the Wheel
Place the wheel back onto the hub and tighten the lug nuts by hand. Lower the vehicle and fully tighten the lug nuts using a torque wrench to the specified torque.
11. Final Checks
Double-check all bolts and nuts are properly tightened. Rotate the wheel by hand to ensure it spins smoothly without any play.
Troubleshooting Tips
- If you encounter difficulty removing the hub assembly, spray penetrating oil around the bolts and let it sit for a few minutes.
- If the new wheel bearing is not seated properly, it may make a clicking noise. Remove the bearing and reinstall it, ensuring it is fully seated.
- If the noise persists after replacing the wheel bearing, it may be an issue with other components, such as the CV joint or brake pads.
