Solution

1. Preparation

Tools Required: Jack and jack stands, tire iron, OBD-II scanner, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Balance Tires

Sub-steps:
1. Remove all four wheels using the tire iron.
2. Inspect tires for uneven wear, bulges, or damage.
3. Have tires balanced at a professional shop if necessary.
4. Reinstall wheels, ensuring lug nuts are torqued to the manufacturer's specifications (typically 80-100 ft-lbs for F-150s).

3. Check Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop for a complete alignment check.
2. Adjust the camber, caster, and toe angles as needed according to manufacturer specifications.

4. Inspect Driveshaft and U-joints

Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Visually inspect the driveshaft for any signs of damage or bending.
3. Check U-joints by attempting to twist them; they should move freely without play.
4. Replace any damaged driveshaft components or U-joints as necessary.

5. Check Engine and Transmission Mounts

Sub-steps:
1. Inspect all engine and transmission mounts for cracks or severe wear.
2. Replace any mounts that show signs of failure.
3. Use a torque wrench to ensure bolts are tightened to manufacturer specifications.

6. Final Assembly

Sub-steps:
1. Reinstall any components removed during inspection.
2. Reconnect the battery and ensure all electrical connections are secure.
