Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, wheel balancer, alignment machine.
Ensure the vehicle is on a flat surface and parked securely.
Disconnect the battery before working on any electrical components.

2. Tire Inspection and Adjustment

Sub-steps:
1. Remove the wheel covers, if applicable.
2. Check tire pressure and inflate to the manufacturer's specifications.
3. Inspect tires visually for cracks, bulges, or uneven tread wear.
4. If uneven wear is found, rotate or replace the tires as necessary.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel from the vehicle using a jack.
2. Mount the wheel on a wheel balancer.
3. Follow the machine's instructions to balance the wheel, adding weights as needed.
4. Reinstall the wheel to the vehicle and torque the lug nuts to the specified value (usually around 90-100 ft-lbs for Skoda).

4. Suspension and Wheel Bearing Inspection

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Check the wheel bearings by grabbing the wheel at 12 and 6 o'clock and rocking it; any movement indicates worn bearings.
3. Replace any worn suspension components or wheel bearings as needed.

5. Alignment

Sub-steps:
1. Place the vehicle on a wheel alignment rack.
2. Perform a four-wheel alignment according to the manufacturer's specifications.
3. Adjust the toe, camber, and caster as necessary.
