2. Inspect and Tighten Exhaust Components

Use a socket set to check and tighten all exhaust bolts and clamps.
If any components are damaged, remove them using a socket set and replace with new parts.

3. Replace Heat Shields (if necessary)

If heat shields are loose, tighten them with a socket set.
If damaged, remove the heat shield using a wrench, and replace it with a new one.

4. Inspect and Replace Suspension Components

If worn suspension parts are found, lift the vehicle using a jack and secure with jack stands.
Remove the wheel to access struts and control arms.
Replace worn components with new parts, ensuring proper torque specifications are followed (consult service manual for specific torque values).
