Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Inspect and Balance Tires

Remove the wheel covers or hubcaps if applicable.
Use a tire pressure gauge to check tire pressures; inflate to the manufacturer’s specifications if necessary.
If tires are worn unevenly or damaged, consider replacing them.
Take the vehicle to a tire shop for balancing if no visible issues are found.

3. Check Wheel Lug Nut Torque

Use a torque wrench to check the lug nut torque.
Tighten lug nuts to the manufacturer's specified torque value (typically 100-150 ft-lbs for Mustangs).
Recheck after a short test drive.

4. Inspect Suspension Components

Raise the vehicle using a jack and secure it with jack stands.
Inspect control arms, bushings, ball joints, and struts for signs of wear or damage.
Replace any worn components.

5. Inspect Driveshaft and CV Joints

Inspect the driveshaft for any visible damage or excessive play.
Check CV joints for torn boots or grease leakage.
Replace any damaged driveshaft or CV joints as necessary.
