Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety if working on electrical components.

2. Tire Inspection and Rotation

Sub-steps:
1. Remove the lug nuts using a socket wrench and take off the affected wheel.
2. Inspect the tire for bulges, uneven wear, and check the air pressure.
3. Rotate tires if uneven wear is present, moving front tires to the rear and vice versa.
4. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 100-150 lb-ft for F-150).

3. Suspension Inspection

Sub-steps:
1. Visually inspect the control arms, bushings, and shocks for signs of wear or damage.
2. Replace any damaged components with OEM parts.
3. Ensure that all suspension bolts are tightened to the manufacturer’s torque specifications.

4. Driveshaft and U-Joint Inspection

Sub-steps:
1. Inspect the driveshaft for dents, bends, or signs of damage.
2. Check U-joints for play or wear; if worn, replace the U-joint.
3. Reassemble any components and ensure they are torqued to specification.

5. Final Assembly and Testing

Sub-steps:
1. Reconnect the battery and start the engine.
2. Test drive the vehicle to ensure that the shaking has been resolved and the vehicle operates smoothly.
