Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, tire balancing machine.
Raise the vehicle using a jack and secure it with jack stands.
Ensure the workspace is safe and free from hazards.

2. Tire Inspection

Sub-steps:
1. Remove the wheels using a socket set.
2. Inspect tires for uneven wear patterns, bulges, or other damage.
3. Measure tire tread depth; replace if below the minimum requirement (usually 2/32 inches).

3. Tire Balancing

Sub-steps:
1. Mount the tires on a tire balancing machine.
2. Spin the tires and identify any unbalanced areas.
3. Add wheel weights as needed to achieve proper balance.

4. Wheel Alignment

Sub-steps:
1. After balancing, check the alignment using an alignment machine.
2. Adjust camber, caster, and toe settings according to manufacturer specifications.

5. Driveshaft and Axle Inspection

Sub-steps:
1. Inspect the driveshaft for any bends or dents.
2. Check the universal joints for excessive play or wear.
3. Inspect the axles for any cracks or excessive wear.

6. Reinstallation

Sub-steps:
1. Reinstall the wheels using a torque wrench to tighten the lug nuts to the manufacturer's specified torque (typically 76-95 ft-lbs for Highlander).
2. Lower the vehicle and perform a test drive to ensure vibrations have been resolved.
