Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety when working on electronic components.

2. Tire Inspection and Balancing

Remove the wheel cover and loosen the lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel and inspect the tire for uneven wear or damage.
If tires are damaged, replace them with new ones.
Take the wheel to a tire shop for balancing if necessary. Reinstall after balancing.

3. Suspension Component Inspection

Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
If any components are worn, replace them with OEM or quality aftermarket parts.
Reassemble any removed components and tighten bolts to manufacturer specifications, usually around 75-85 ft-lbs for suspension components.

4. Driveshaft and Axle Inspection

Inspect the driveshaft for any visible damage or bending; replace if necessary.
Check the universal joints for excessive play; replace if worn.
Ensure the axle is properly aligned and installed; adjust if necessary.

5. Reassembly and Completion

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications, typically 100-150 ft-lbs for the Mustang.
Reconnect the battery and ensure all tools are removed from the work area.
