Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Tire Inspection

Sub-steps:
- Check tire pressures and inflate to the manufacturer's specifications if necessary.
- Inspect tires for uneven wear, bulges, or damage; replace if necessary.
- Rotate tires if wear is uneven to promote even tread.

3. Drivetrain Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Visually inspect the driveshaft for signs of damage or excessive play in the joints.
- Check for any loose or damaged mounts on the motor or transmission.

4. Wheel Balance and Alignment

Sub-steps:
- Remove the wheels and take them to a shop for balancing; re-install after balancing.
- Check the alignment specifications and adjust as necessary using an alignment machine.

5. Verification

Test drive the vehicle to ensure that the shaking has been resolved.
Monitor the vehicle for any abnormal noises during acceleration.
Re-scan the vehicle for error codes to ensure no new codes have appeared.
