Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, lug wrench, alignment tool, vibration analyzer (if available).
Safely park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection and Pressure Adjustment

Sub-steps:
1. Remove the hubcaps or wheel covers (if applicable).
2. Use the tire pressure gauge to check the tire pressure on all four tires; adjust to the manufacturer's recommended pressure.
3. Inspect the tires for signs of uneven wear, bulges, or damage.
4. Rotate tires if uneven wear is evident.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Take the wheels to a tire shop for balancing or use a wheel balancing machine.
3. Reinstall the wheels once balanced, ensuring lug nuts are torqued to the manufacturer's specifications (typically 76-80 ft-lbs for Toyota).

4. Alignment Check

Sub-steps:
1. After balancing, perform a wheel alignment using an alignment machine.
2. Adjust camber, caster, and toe angles as needed to meet manufacturer specifications.
3. Test drive to confirm alignment correction.

5. Suspension and Driveline Inspection

Sub-steps:
1. Visually inspect the suspension components (shocks, struts, bushings) for wear and damage.
2. Inspect the driveshaft and CV joints for play or wear.
3. Replace any worn or damaged components as necessary.
