Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, flashlight.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to ensure safety during inspection.

2. Inspect and Repair Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the entire exhaust system for any rust, holes, or loose connections.
3. If a leak is found, replace the damaged section with a suitable exhaust patch or new pipe.
4. Tighten any loose clamps or bolts securing the exhaust components.

3. Check and Replace Engine Mounts (if damaged)

Sub-steps:
1. Inspect engine mounts for cracks or deterioration.
2. If damaged, use a socket set to remove the bolts securing the engine mount to the engine block and frame.
3. Replace with new engine mounts and torque to manufacturer specifications (typically around 30-50 ft-lbs).

4. Inspect Drivetrain Components

Sub-steps:
1. Check CV joints for torn boots or excessive play.
2. If damaged, remove the CV axle with a socket set and replace with a new one.
3. Inspect the driveshaft for any signs of wear or imbalance; replace if needed.

5. Reconnect Battery

Reconnect the battery terminals and ensure they are tight.
