Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Wheel chocks
- Torque wrench
- Socket set
- Pry bar
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts with a socket wrench before lifting the vehicle.
Jack up the vehicle and place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Bearing

Visual Inspection: Check the wheel hub and bearing assembly for any signs of wear or damage.
Remove the Hub:
- Remove any dust caps or retaining clips.
- Use a socket set to unbolt the hub assembly from the steering knuckle.
- If necessary, use a pry bar to carefully separate the hub from the knuckle.
Replace Bearing:
- If the bearing is damaged, use a bearing puller to remove it from the hub.
- Install the new bearing using a press or hammer, ensuring it is seated properly.
Reassemble:
- Place the hub back onto the steering knuckle.
- Torque the bolts to manufacturer specifications (usually around 70-90 ft-lbs).
- Replace any dust caps or retaining clips.

4. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically around 100-120 ft-lbs).

5. Test Drive

After the repair, test drive the vehicle to ensure that the noise and symptoms have been resolved.
