Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, mechanic's stethoscope, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before working underneath.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Wheel Bearing

Remove Brake Components:
- Remove the brake caliper and hang it securely without putting strain on the brake line.
- Take off the brake rotor.
Remove Wheel Hub Assembly:
- Disconnect any ABS sensor wiring if present.
- Remove the retaining bolts for the wheel hub using a socket set.
- Carefully pull out the hub assembly from the knuckle.
Install New Wheel Bearing:
- Press the new wheel bearing into the hub assembly using a hydraulic press if necessary.
- Reinstall the hub assembly into the knuckle, ensuring it is seated properly.
Reassemble Brake Components:
- Reattach the brake rotor and caliper, tightening bolts to the manufacturer's specified torque settings.

4. Reinstall Wheel

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