Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, OBD-II scanner, torque wrench, tire pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during inspections.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Check tire pressure using a tire pressure gauge; inflate to manufacturer specifications if necessary.
3. Inspect tires for uneven wear patterns, bulges, or cracks.
4. Replace any damaged tires as necessary.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel from the vehicle.
2. Take the wheel to a tire shop for professional balancing.
3. Reinstall the wheel, ensuring that lug nuts are torqued to manufacturer specifications (e.g., 120 Nm).

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the driveshaft for any signs of wear, such as cracks or excessive play.
3. Check CV joints for grease leaks or damage.
4. Replace any damaged components as necessary.

5. Suspension Component Check

Sub-steps:
1. Visually inspect suspension components, including control arms and bushings, for wear or damage.
2. Replace any worn suspension parts.
3. Check alignment and adjust as necessary.
