Solution

1. Tire Inspection

Sub-steps:
1. Check tire pressure using a tire gauge; inflate to recommended PSI if necessary.
2. Inspect tires for uneven wear or bulges; rotate or replace as needed.
3. If tires are unbalanced, take the vehicle to a tire shop for balancing.

2. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Visually inspect control arms, bushings, and struts for wear or damage.
3. Replace any worn or damaged suspension components as necessary.

3. Engine and Transmission Mount Check

Sub-steps:
1. Open the hood and visually inspect the mounts for cracks or excessive wear.
2. Use a pry bar to check for excessive movement in the mounts.
3. Replace any faulty engine or transmission mounts; torque new mounts to manufacturer specifications.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft and CV joints for signs of wear or damage.
2. Check for fluid leaks around the transmission and differential.
3. Replace any damaged driveshaft components or seals.
