Disconnect the battery to avoid electrical issues.

2. Inspect and Repair the Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust system from the engine to the tailpipe for any visible damage or loose connections.
3. If leaks are found, replace damaged components (e.g., gaskets, clamps, mufflers).
4. Tighten any loose bolts or clamps within the exhaust system.

3. Engine Mount Inspection

Sub-steps:
1. Locate the engine mounts and visually inspect for cracks or separation.
2. If damaged, follow the manufacturer's guidelines to replace engine mounts.
3. Use a torque wrench to ensure bolts are tightened to manufacturer specifications.
