Sub-steps:
- Remove the front wheels to access the CV joints and axles.
- Inspect CV boots for any tears or grease leaks.
- Check for play in the axles by trying to move them in and out; replace if any damage is found.
- If necessary, replace the CV joints or axles as per the service manual.

4. Check Exhaust and Undercarriage

Sub-steps:
- Visually inspect the exhaust system for loose or damaged components.
- Tighten any loose bolts and replace damaged hangers.
- Ensure no parts are hitting the undercarriage when the vehicle is in reverse.

5. Test Drive
