Solution

1. Tire Inspection and Adjustment

Sub-steps:
- Check tire pressure using a tire pressure gauge; inflate to the manufacturer's recommended PSI if necessary.
- Inspect all tires for bulges, cuts, or uneven tread wear; replace any damaged tires.

2. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using a socket set.
- Mount the wheel on a wheel balancer and adjust weights as necessary to achieve balance.
- Reinstall the wheel, ensuring proper torque (typically around 90-110 ft-lbs for Porsche).

3. Wheel Alignment

Sub-steps:
- Use an alignment tool to measure the angles of the wheels.
- Adjust the camber, caster, and toe angles according to Porsche specifications.
- Test drive the vehicle post-alignment to ensure proper handling.

4. Suspension Inspection

Sub-steps:
- Visually inspect suspension components for cracks or wear.
- Replace any worn components such as bushings or struts with OEM parts.
- Torque the suspension components to manufacturer specifications.

5. Driveshaft and CV Joint Check

Sub-steps:
- Lift the vehicle and inspect the driveshaft for any visible damage.
- Check CV joints for grease leaks or wear; replace if necessary.
- Reinstall any removed components securely, following torque specifications.
