Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool down if it was driven recently.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear patterns; replace tires if necessary.
Replace Tires (if needed):
- Use a tire iron to loosen lug nuts.
- Lift the vehicle with a jack and secure with jack stands.
- Remove the tires and mount new ones, ensuring proper alignment of the valve stems.
- Torque lug nuts to the manufacturer's specification (typically around 100-120 ft-lbs).
- Re-check tire pressure after installation.

3. Wheel Balancing

Mount the tires on a balancing machine.
Adjust weights based on the machine's readings to ensure even distribution.
Reinstall balanced wheels on the vehicle.

4. Wheel Alignment

Utilize a laser alignment tool to check if the wheels are aligned within manufacturer specifications.
Adjust camber, toe, and caster settings as needed, following the vehicle's service manual for specific measurements.

5. Suspension Inspection and Repairs

Inspect suspension components for wear or damage:
- Check bushings for cracks or separation.
- Look for leaks in shock absorbers.
Replace damaged components as required, following manufacturer specifications for torque values.
