Safety gear (gloves, goggles) should be worn.

2. Inspect Suspension Components

Sub-steps:
- Use a jack and jack stands to lift the vehicle safely.
- Check for any damaged struts, control arms, or bushings; replace if necessary.
- Inspect sway bar links for wear; replace if they show signs of damage.

3. Inspect Drivetrain Components

Sub-steps:
- Check the CV joints for wear or damage; replace if torn or worn.
- Inspect the driveshaft for any signs of damage or imbalance; replace if necessary.
- Ensure that all drivetrain bolts are properly torqued to the manufacturer’s specifications.

4. Examine Exhaust System

Sub-steps:
- Inspect the exhaust system for any loose or damaged hangers or pipes.
- Check for any leaks or holes in the exhaust that could cause noise; repair or replace as needed.

5. Reassemble and Lower the Vehicle

Sub-steps:
- If any components were removed, reattach them securely.
- Lower the vehicle and remove jack stands.
- Tighten any bolts to the specified torque values.
