Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather all necessary tools and parts.

2. Inspect and Replace Tires

Sub-steps:
1. Check the tire pressure using a tire pressure gauge and inflate to the recommended PSI.
2. Inspect all tires for uneven wear; replace any tires that are worn out.
3. If needed, balance the tires using a tire balancer.

3. Inspect and Replace Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and struts for damage or excessive wear.
2. Replace any damaged suspension components using a socket set.
3. Perform a wheel alignment after replacing any suspension parts.

4. Check and Replace Driveshaft or CV Joints

Sub-steps:
1. Raise the vehicle on jack stands and remove the wheels for easier access.
2. Inspect the driveshaft and CV joints for any tears or leaks.
3. Replace any faulty CV joints or driveshafts as necessary using a torque wrench for proper installation.

5. Inspect Engine Mounts

Sub-steps:
1. Visually inspect engine mounts for cracks or signs of failure.
2. Remove and replace any damaged engine mounts, ensuring proper torque specifications are followed.
3. Test the engine for vibrations after replacing the mounts.
