Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Secure Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Inspect control arms and bushings for signs of wear or damage.
- If any components are loose, tighten them to the manufacturer’s torque specifications.
- Replace worn or damaged bushings as needed.
- Use a pry bar to check for excessive play in suspension joints.

3. Examine the Exhaust System

Tools Required: Wrench set, flashlight
Inspect the exhaust system from the manifold to the tailpipe.
- Check for loose hangers or clamps.
- Tighten any loose bolts or connections.
- Look for signs of rust or holes in the exhaust, which may need patching or replacement.

4. Test Drive and Further Inspection

Reconnect the battery.
Conduct a test drive to confirm if the popping sound persists.
If the sound continues, further investigate the drivetrain components (CV joints, differential, etc.) for wear and damage.
