Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Tire Inspection

Remove the wheel covers if applicable.
Check tire pressure and inflate to the recommended PSI.
Inspect tires for uneven wear patterns or damage; replace if necessary.
Balance tires if they are out of balance using a tire balancing machine.

3. Suspension Component Inspection

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect suspension components (tie rods, shocks, control arms) for any signs of wear or damage.
Replace any worn or damaged components as necessary.

4. Driveshaft and CV Joint Examination

Inspect the driveshaft for visible damage and ensure it is securely mounted.
Check the CV joints for leaks or torn boots; replace if damaged.

5. Engine and Transmission Mount Check

Inspect the engine and transmission mounts for cracks or deterioration.
Replace any faulty mounts to minimize drivetrain vibrations.

6. Alignment and Balance Verification

Perform a wheel alignment using an alignment machine.
Ensure proper wheel balance using a balancing machine; adjust as necessary.
