Solution

1. Tire Inspection and Replacement

Sub-steps:
- Inspect each tire for signs of damage, bulges, or punctures.
- Measure tire tread depth to ensure it meets safety standards.
- Replace any damaged tires with OEM or compatible replacements.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a wheel balancer machine.
- Identify any imbalances and add wheel weights as needed.
- Reinstall the wheels and torque lug nuts to manufacturer's specifications (typically 130 Nm for Cayenne).

3. Suspension and Steering Component Inspection

Sub-steps:
- Use a jack and jack stands to lift the vehicle safely.
- Visually inspect control arms, bushings, and tie rods for wear or damage.
- Replace any worn components with OEM parts.
- Ensure that all fasteners are tightened to the specified torque values.

4. Wheel Bearing Inspection and Replacement

Sub-steps:
- Remove the wheel and brake caliper to access the wheel hub.
- Inspect the wheel bearing for play or roughness.
- If defective, replace the wheel bearing using a bearing puller and press.
- Reassemble the brake caliper and wheel, torquing to specifications.
