Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Repair Exhaust System

Tools Required: Socket set, exhaust pipe cutter (if necessary), wrench set.
Sub-steps:
1. Raise the vehicle using jack stands for safety.
2. Visually inspect the exhaust system from the engine to the tailpipe for any signs of damage or rust.
3. If a leak is found, use the exhaust pipe cutter to remove the damaged section and install a new pipe or muffler using clamps.
4. Tighten all connections securely to avoid future leaks.

3. Inspect and Repair Drivetrain Components

Tools Required: Torque wrench, sockets, and screwdrivers.
Sub-steps:
1. Inspect CV joints and the driveshaft for any signs of wear or damage.
2. If any components are damaged, remove and replace them with new parts.
3. Ensure all bolts are torqued to the manufacturer's specifications.

4. Reconnect Battery and Test

Reconnect the battery and start the engine.
Allow the engine to idle and listen for any abnormal noises.
Drive the vehicle to ensure the noise has been resolved.
