Solution

1. Tire Inspection

Sub-steps:
- Remove wheel covers if applicable.
- Visually inspect all tires for damage or uneven wear.
- Measure tread depth using a tread depth gauge; replace tires if tread is below 2/32".

2. Tire Balancing

Sub-steps:
- Remove the wheel and tire assembly from the vehicle using a socket set.
- Mount the tire on a balancing machine.
- Follow the machine's instructions to balance the tire; add weights as necessary.
- Reinstall the balanced tire on the vehicle, ensuring to torque the lug nuts to the manufacturer’s specifications (typically around 80-100 lb-ft).

3. Wheel Alignment

Sub-steps:
- Use an alignment rack to measure the alignment angles.
- Adjust toe, camber, and caster angles to meet manufacturer specifications.
- Test drive the vehicle to ensure proper handling post-alignment.

4. Suspension Inspection

Sub-steps:
- Lift the vehicle using a hydraulic jack and secure it with jack stands.
- Visually inspect all suspension components for signs of wear or damage.
- Replace any worn or damaged components, such as control arms or bushings, as necessary.
