Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, OBD-II scanner, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.

2. Tire Inspection

Sub-steps:
1. Remove the hubcaps or wheel covers if necessary.
2. Inspect each tire for uneven wear patterns, bulges, or punctures.
3. Measure tire pressure using a tire pressure gauge and inflate to the recommended PSI if low.
4. If any damage is found, consider replacing the tire.

3. Wheel Alignment and Suspension Check

Sub-steps:
1. Lift the vehicle using a floor jack and secure it with jack stands.
2. Inspect the suspension components (control arms, bushings, struts) for wear or damage.
3. Check for proper alignment by measuring distances from the front and rear tires, or have a professional alignment performed.

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any bends or cracks.
2. Check CV joints for torn boots or excessive play by wiggling the joints.
3. If damage is found, replace the driveshaft or CV joints as necessary.

5. Reassemble and Test

Sub-steps:
1. Reinstall wheels and torque lug nuts to manufacturer specifications.
2. Lower the vehicle and remove the jack stands.
3. Start the engine and take the vehicle for a test drive to ensure the shaking is resolved.
