Solution

1. Tire Inspection and Replacement

Sub-steps:
- Check the tire pressure using a tire pressure gauge and inflate to the recommended levels.
- Inspect the tread for uneven wear; replace any damaged or worn tires.
- Rotate tires if uneven wear is observed to promote even wear.

2. Suspension Component Inspection

Sub-steps:
- Raise the vehicle with a jack and secure it on jack stands.
- Inspect all suspension components (control arms, bushings, and struts) for damage or excessive play.
- Replace any worn or damaged components as needed.

3. Driveshaft and CV Joint Evaluation

Sub-steps:
- Visually inspect the driveshaft for any visible damage or rust.
- Check CV joints for cracks or tears in the rubber boots.
- Replace any damaged CV joints or driveshaft components.

4. Engine and Transmission Mounts Replacement

Sub-steps:
- Locate the engine and transmission mounts and visually inspect for cracks or separation.
- Use a socket set to remove the bolts securing the mounts and replace them with new mounts.
- Torque the bolts to the manufacturer's specifications.

5. Wheel Balancing and Alignment

Sub-steps:
- Take the vehicle to a professional for wheel balancing.
- Have a 4-wheel alignment performed to ensure proper alignment of the tires.
- Confirm that no vibrations are present after balancing and alignment.
