Solution

1. Preparation

Gather tools: socket set, torque wrench, pry bar, jack stands, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Remove the wheel corresponding to the side making the noise.
- Examine the CV joint boot for tears or grease leakage.
Replace if Necessary:
- Use a socket set to remove the axle nut.
- Disconnect the lower control arm from the knuckle if necessary for better access.
- Slide the CV axle out and replace it with a new one. Ensure the new CV joint is properly lubricated.
- Reassemble all components and torque the axle nut to manufacturer specifications (typically 180 Nm).

3. Check and Replace Suspension Components

Inspect Suspension:
- Use a pry bar to check for play in the strut mounts and sway bar links.
Replace if Necessary:
- Remove any damaged sway bar links using a socket set.
- Replace with new links, ensuring they are torqued to manufacturer specifications.
- Inspect strut mounts and replace them if they show signs of wear.

4. Final Inspection and Reassembly

Reinstall the wheel and lower the vehicle.
Check all fasteners and components to ensure proper installation.
Test the vehicle to ensure the popping sound has been eliminated.
