Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Tire Inspection and Replacement

Sub-steps:
- Inspect each tire for signs of damage, uneven wear, or low pressure.
- Replace any damaged tires or inflate tires to the manufacturer's recommended pressure.
- If uneven wear is detected, consider rotating or replacing tires as necessary.

3. Suspension Inspection and Repair

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect all suspension components, including control arms, struts, and bushings for wear.
- Replace any worn or damaged components with OEM or quality aftermarket parts.

4. Engine and Transmission Mount Inspection

Sub-steps:
- Visually inspect engine and transmission mounts for cracks or separation.
- Use a pry bar to check for excessive movement of the mounts.
- Replace any faulty mounts with new ones, ensuring proper torque specifications are followed (typically 30-50 ft-lbs, depending on the vehicle).

5. Reassemble and Test

Sub-steps:
- Reconnect the negative battery terminal.
- Lower the vehicle and perform a test drive to ensure the shaking or vibration has been resolved.
- Monitor for any abnormal sounds or additional vibrations during the test drive.
