Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Socket set
- Wheel chocks
- Safety gloves
- Safety goggles
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and securely support the vehicle with jack stands before working under it.

2. Remove the Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel with the lug wrench while the vehicle is still on the ground.
2. Jack up the vehicle using the jack, then secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect the Wheel Bearing

Sub-steps:
1. Look for any visible signs of damage, rust, or contamination in the bearing area.
2. Check the hub assembly for any cracks or distortion.
3. Manually spin the hub or rotor and listen for grinding noises or roughness.

4. Test Bearing Play

Sub-steps:
1. With the wheel removed, grasp the hub at the 12 and 6 o'clock positions.
2. Pull and push to feel for any play; there should be minimal to no movement.
3. If play is detected, the bearings may need to be replaced.

5. Reassemble

Sub-steps:
1. Reinstall the wheel onto the vehicle, ensuring proper alignment with the hub.
2. Hand-tighten the lug nuts to secure the wheel.
3. Lower the vehicle off the jack stands and fully tighten the lug nuts to the manufacturer’s specified torque (usually around 76 lb-ft for Tacoma).
