Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Always wear safety glasses and gloves when working on vehicles.

2. Tire Inspection and Balance

Tools Required: Tire pressure gauge, tire balancing machine.
Check tire pressures; inflate to manufacturer's specifications if low.
Inspect all tires for bulges, cracks, or uneven wear.
If necessary, take the vehicle to a tire shop for professional balancing.

3. Wheel Lug Nut Torque

Tools Required: Torque wrench.
Check lug nut torque using a torque wrench; tighten to the manufacturer's specified torque (typically around 100-150 ft-lbs for F-150).
Recheck torque after the first 100 miles of driving.

4. Suspension Components Inspection

Tools Required: Jack and jack stands, socket set.
Safely lift the vehicle and secure it with jack stands.
Inspect control arms, bushings, and ball joints for wear or damage.
Replace any worn components.

5. Driveshaft Examination

Tools Required: Socket set, pry bar.
Inspect the driveshaft for any visible damage, including dents or rust.
Check U-joints for play or wear; replace if necessary.

6. Professional Diagnostic (if needed)

If the issue persists, consider taking the vehicle to a qualified technician for a detailed diagnostic check, especially if any error codes were found.
