6. Reinstall any engine covers removed.

3. Inspect Tires and Suspension

Sub-steps:
1. Elevate the vehicle using a jack and secure it with jack stands.
2. Inspect all tires for uneven wear patterns, bulges, or foreign objects embedded in the tread.
3. If any tire shows excessive wear or damage, replace it with a compatible tire.
4. Check wheel wells for signs of tire rubbing against any components.
5. Adjust suspension components if misalignment is causing tire contact.

4. Check Exhaust System

Sub-steps:
1. Inspect the exhaust manifold and pipes for any visible cracks or holes that could lead to exhaust leaks.
2. Use a flashlight to check for any signs of melted or damaged components near the exhaust.
