Engage the parking brake and allow the vehicle to cool.

2. Inspect Exhaust Components

Tools Required: Socket set, flashlight, car jack, jack stands.
Sub-steps:
1. Lift the vehicle using a car jack and secure it with jack stands.
2. Inspect the entire exhaust system from the engine manifold to the tailpipe for any loose brackets, cracks, or holes.
3. Tighten any loose bolts or clamps.
4. Replace any damaged sections of the exhaust system as needed.

3. Check Engine Mounts

Tools Required: Wrench set, pry bar.
Sub-steps:
1. Inspect the engine mounts for cracks or rubber deterioration.
2. Use a pry bar to lift the engine slightly and observe if the mounts flex excessively.
3. Replace any worn or damaged engine mounts.

4. Inspect Driveshaft and CV Joints

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Check the driveshaft for any signs of bending or damage.
