2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure that the vehicle is stable before proceeding with any repairs.

3. Inspect Suspension Components

Struts and Shocks: Check for any oil leaks on the struts or shocks; these may need replacement.
Control Arms and Bushings: Inspect for cracks or excessive wear; replace if necessary.
Ball Joints: Verify the integrity of the ball joints; replace if there is excessive play.

4. Replace Damaged Components

Remove Old Parts: Using the socket set, remove the damaged or worn suspension components.
Install New Parts: Follow the manufacturer's specifications for installing new parts. Torque nuts and bolts to the specified values.
Reassemble: Carefully reassemble any components that were removed during inspection.

5. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Perform a final check on all fasteners to ensure they are secure.

6. Test Drive

Conduct a test drive to verify that the noise has been resolved and that the suspension is functioning properly.
