Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Safety Warnings: Ensure the vehicle is secured with jack stands before crawling underneath.

2. Inspect and Replace Suspension Components

Inspect Components:
- Use a flashlight to inspect the control arms and bushings for signs of tears or wear.
- Check the strut mounts for any signs of corrosion or damage.
Replace Worn Parts:
- If any components are damaged, remove the necessary bolts using a socket set.
- Replace the worn parts with new ones, ensuring all bushings are properly aligned.
- Torque all bolts to the manufacturer’s specifications (check the repair manual for specific torque values).

3. Inspect and Secure Exhaust Components

Check Exhaust System:
