1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Repair Exhaust System

Tools Required: Wrench set, jack stands, safety goggles.
Sub-steps:
1. Use a jack to lift the vehicle and secure it with jack stands.
2. Visually inspect the exhaust system for any visible leaks, cracks, or loose connections.
