Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electronic components.

2. Tire Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle.
2. Mount the tire on the balancing machine and spin it to identify imbalances.
3. Add wheel weights to the rim as needed to achieve balance.
4. Reinstall the wheel on the vehicle, ensuring lug nuts are tightened to the manufacturer's torque specifications (typically 100-150 lb-ft for Mustang).

3. Wheel Alignment

Sub-steps:
1. Use a laser alignment tool to check the front and rear wheel alignment.
2. Adjust the camber, caster, and toe settings according to the manufacturer’s specifications.
3. Test drive the vehicle to confirm alignment is correct.

4. Tire Inspection

Sub-steps:
1. Check for uneven wear patterns, sidewall bulges, or embedded debris.
2. Rotate tires if uneven wear is detected, or replace damaged tires.
3. Ensure proper tire pressure (typically around 32-35 psi for the Mustang).

5. Suspension Inspection

Sub-steps:
1. Visually inspect all suspension components, including control arms, struts, and bushings for wear or damage.
2. Replace any worn or damaged parts with OEM or high-quality aftermarket components.
3. Recheck the alignment after replacing suspension components.
