Solution

1. Preparation

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

2. Tire Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take the wheels to a tire shop or use a tire balancing machine.
3. Balance each tire according to specifications.
4. Reinstall the wheels, ensuring lug nuts are torqued to the manufacturer’s specifications (typically 100-150 lb-ft for Mustangs).

3. Tire Inspection

Sub-steps:
1. Check tire pressure with a tire pressure gauge and inflate to the recommended PSI (usually around 32-35 PSI for the Mustang).
2. Inspect tires for uneven wear, bulges, or damage. Replace if necessary.

4. Wheel Alignment

Sub-steps:
1. Drive the vehicle to a professional alignment shop, or use a wheel alignment tool.
2. Adjust the alignment to the manufacturer’s specifications.

5. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components for cracks or wear.
2. Replace any worn or damaged bushings, control arms, or struts as needed.
