Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Tire Balancing

Sub-steps:
1. Remove the wheel from the affected area using a lug wrench.
2. Mount the wheel on a tire balancer machine.
3. Follow the machine's instructions to determine the balance weights required.
4. Attach the necessary weights to the wheel rim as indicated.
5. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 100-150 lb-ft for Mustang).

3. Inspect and Replace Tires

Sub-steps:
1. Check for uneven wear patterns and bulges.
2. Replace any damaged tires with new ones of the same specifications.
3. Ensure tires are inflated to the recommended pressure (typically 30-35 PSI for Mustang).

4. Suspension Inspection and Repair

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect control arms, bushings, and tie rod ends for play or wear.
3. Replace any worn or damaged components.
4. Recheck all bolts for proper torque settings.

5. Wheel Alignment

Sub-steps:
1. Drive the vehicle to an alignment shop or use an alignment tool if available.
2. Adjust alignment settings to match manufacturer specifications (typically ±0.5° camber and ±0.1° toe).
3. Test drive the vehicle to ensure proper handling.
