Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Ensure the vehicle is on a level surface and secure it with wheel chocks.
2. Remove the wheel covers or hubcaps if applicable.
3. Inspect each tire for signs of wear, bulges, or punctures.
4. Check tire pressure using a tire pressure gauge and inflate to the manufacturer's recommended PSI.
5. If any tire is damaged or excessively worn, replace it with a new tire.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Take the wheels to a tire shop for professional balancing.
3. Ensure that balancing weights are properly installed according to specifications.
4. Reinstall the wheels on the vehicle, tightening the lug nuts to the manufacturer's torque specification (typically 76 lb-ft for Toyota Highlanders).

3. Wheel Alignment

Sub-steps:
1. After ensuring the wheels are balanced, take the vehicle to an alignment shop.
2. Have the alignment checked and adjusted according to manufacturer specifications.
3. Verify that the alignment is within the specified ranges for both front and rear axles.

4. Suspension Component Inspection

Sub-steps:
1. Raise the vehicle on a hydraulic lift or jack stands to access the suspension components.
2. Inspect control arms, bushings, and struts for wear or damage.
3. Replace any worn or damaged components as necessary; use OEM or high-quality aftermarket parts.
4. Reassemble all components and ensure all hardware is tightened to specification.
