Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for proper tread depth using a tread depth gauge.
- Look for cracks, bulges, or foreign objects in the tires.
Replace Tires (if necessary):
- Remove wheel covers (if applicable) and loosen lug nuts with a socket wrench.
- Jack up the vehicle and secure it with jack stands.
- Remove the wheels and install new tires, ensuring they are correctly mounted.
- Torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs for most VW models).

3. Wheel Alignment

Adjust Alignment:
- Set up the vehicle on a wheel alignment machine.
- Adjust camber, caster, and toe settings to align with manufacturer's specifications.
- Test drive the vehicle again to confirm stability.

4. Suspension Inspection and Repair

Inspect Suspension:
- Check struts, shocks, and bushings for wear or damage.
- Replace any worn or damaged components with OEM parts.
- Ensure all bolts are torqued to specifications.
