Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a stable surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Inspect the Exhaust System

Use a jack to lift the vehicle and secure it with jack stands.
Visually inspect the exhaust pipes, muffler, and catalytic converter for any visible holes or rust.
If any damage is found, proceed to replace the affected components.

3. Check Engine Mounts

Locate the engine mounts (usually positioned at the front, rear, and sides of the engine).
Use a socket set to remove the bolts securing the engine mounts.
Inspect the mounts for cracks or excessive wear.
Replace any damaged mounts with new ones, securing them to the specified torque.

4. Inspect Drivetrain Components

Check the CV joints and axles by visually inspecting for torn boots or excessive play.
If damaged, remove the affected axle using a socket set and replace it with a new one.
Ensure all bolts are torqued to manufacturer specifications.

5. Reassemble and Test

Reinstall any components removed during inspection.
Lower the vehicle and start the engine.
Test drive the vehicle to ensure the noise is resolved.
