Solution

1. Preparation

Tools Required: OBD-II scanner, jack, jack stands, tire pressure gauge, socket set, torque wrench
Park the vehicle on a level surface and engage the parking brake.

2. Tire Inspection and Rotation

Sub-steps:
1. Remove the wheel covers or lug nut caps if applicable.
2. Loosen lug nuts slightly (do not remove them) using a socket.
3. Jack up the vehicle and secure it with jack stands.
4. Remove the lug nuts and take off the tires.
5. Inspect tires for uneven wear; consider rotating tires if they are unevenly worn.
6. Reattach the tires and hand-tighten the lug nuts.
7. Lower the vehicle and torque lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Engine Mount Inspection

Sub-steps:
1. Locate the engine mounts (usually near the front and rear of the engine).
2. Visually inspect for cracks or separation in the rubber.
3. Remove bolts securing the engine mount to the engine and frame using a socket.
4. Replace with new mounts if damaged; ensure proper alignment before tightening bolts to manufacturer torque specifications.

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
2. Check CV joints for wear; look for torn or cracked boots.
3. If damaged, replace the driveshaft or CV joints as necessary, following the manufacturer's torque specifications during reinstallation.

5. Final Checks

Sub-steps:
1. Recheck tire pressure on all four tires using a tire pressure gauge, adjusting as necessary to the recommended PSI.
2. Test drive the vehicle to ensure the shaking has been resolved.
