Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the noise is coming from).
Secure it with jack stands for safety.

3. Inspect and Replace Components

A. Suspension Components

Inspect Sway Bar Links:
- Check for any signs of wear; if damaged, remove the bolts using a socket set and replace with new sway bar links.
Inspect Control Arms:
- Look for any damaged bushings; replace if necessary by removing the control arm bolts and installing new bushings.

B. CV Joints

Inspect CV Joints:
- Check for damaged boots or grease leakage. If damaged, remove the axle from the hub and replace the CV joint or axle as necessary.

4. Reassemble and Lower Vehicle

Ensure all components are tightened to the manufacturer’s torque specifications.
Remove jack stands and lower the vehicle back to the ground.

5. Test Drive

Conduct a test drive to ensure the popping noise has been resolved.
