Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, stethoscope (optional), safety glasses.
Ensure vehicle is on a flat surface and that the engine is turned off.

2. Jacking Up the Vehicle

Sub-steps:
- Loosen the lug nuts slightly while the vehicle is still on the ground.
- Use the jack to lift the vehicle and secure it with jack stands.
- Remove the wheel using the lug wrench.

3. Inspect the Wheel Bearing

Sub-steps:
- Place the wheel back on the hub without lug nuts and manually spin it to check for noise or roughness.
- If accessible, apply a stethoscope to the hub assembly while spinning the wheel to listen for abnormal sounds.
- Check for any signs of grease leakage around the bearing seal.

4. Check for Wheel Play

Sub-steps:
- Grasp the wheel at the 12 and 6 o'clock positions and push/pull to check for excessive play.
- Any noticeable movement indicates a failing wheel bearing.

5. Reassemble and Torque

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle off the jack stands.
- Torque the lug nuts to the manufacturer’s specifications (typically around 76 ft-lbs for Highlander).
