Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, torque wrench.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Wheel Bearing

Sub-steps:
1. Remove the brake caliper and rotor to access the wheel hub (use a torque wrench to ensure proper reinstallation).
2. Detach the axle nut using a suitable socket.
3. Remove the wheel hub assembly from the steering knuckle.
4. Clean the mounting surface on the steering knuckle.
5. Install the new wheel bearing by pressing it into the hub, ensuring it is seated correctly.
6. Reassemble the wheel hub assembly and reinstall the axle nut (tighten to manufacturer specifications).
7. Reinstall the brake rotor and caliper, ensuring all bolts are torqued to specifications.

4. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

5. Final Checks

Reconnect the negative battery terminal.
Ensure all components are secured and check for any tools left behind.
