Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, OBD-II scanner, flashlight
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery before starting any repair work on electrical components.

2. Inspect Exhaust System

Sub-steps:
1. Use a jack to lift the vehicle and secure it with jack stands.
2. Visually inspect the exhaust pipes, muffler, and catalytic converter for cracks or loose connections.
3. Tap the exhaust components gently with a rubber mallet to identify any loose parts that may cause noise.
Safety Warning: Allow the exhaust system to cool before inspection to avoid burns.

3. Check Drivetrain Components

Sub-steps:
1. Inspect the CV joints and axles for any visible damage or excessive play.
2. Rotate the wheels while watching the CV joints for any unusual noises or movement.
3. If damage is found, remove the affected CV joint or axle for replacement.

4. Engine Mount Inspection

Sub-steps:
1. Locate and visually inspect the engine and transmission mounts for cracks or deterioration.
2. Use a pry bar to check for excessive movement in the mounts.
3. Replace any worn or damaged mounts to ensure proper alignment and reduce noise.

5. Reconnect Battery and Test Drive

Reconnect the battery and start the vehicle.
Take the vehicle for a test drive to verify that the popping sound is resolved.
