Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Tires

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Sub-steps:
1. Use a tire pressure gauge to check all tires; adjust pressure to the recommended level if necessary.
2. Visually inspect each tire for uneven wear or visible damage.
3. If uneven wear is found, rotate or replace tires as needed.
4. Reinstall tires securely, ensuring lug nuts are torqued to the manufacturer's specifications (usually around 76 ft-lbs for Toyota).

3. Wheel Bearing Inspection and Replacement

Tools Required: Socket set, torque wrench, wheel bearing puller
Sub-steps:
1. Lift the vehicle and remove the wheel.
2. Inspect the wheel bearing for play by shaking the wheel; there should be no movement.
3. If the bearing is worn, use a wheel bearing puller to remove and replace it with a new bearing.
4. Torque the new bearing to the manufacturer's specifications.
5. Reinstall the wheel and lower the vehicle.

4. Driveshaft and CV Joint Check

Tools Required: Socket set, pry bar, torque wrench
Sub-steps:
1. Inspect the driveshaft for any signs of damage or excessive play.
2. Check the CV joints for cracks or leaks; ensure they are lubricated.
3. If repairs are required, replace the damaged driveshaft or CV joint accordingly.
4. Reassemble any components and torque to specifications.
