Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels (depending on the location of the noise) using a socket set.

3. Inspect and Replace Worn Components

Control Arms and Bushings
- Check control arms for cracks or bends.
- If the bushings are worn, remove the control arms by unbolting them and replacing the bushings.
- Torque bolts to manufacturer specifications upon reinstallation.
Ball Joints
- Inspect ball joints for excessive play.
- If they are damaged, remove the ball joint using a ball joint separator tool and replace it.
- Ensure proper torque when reattaching the ball joint.
Strut Mounts
- Inspect strut mounts for wear.
- If worn, remove the strut assembly and replace the mounts.
- Use a torque wrench to tighten bolts to specified torque values.
Sway Bar Links
- Inspect sway bar links for any signs of damage.
- If necessary, remove the links and replace them. Ensure they are securely fastened.

4. Reassemble and Lower Vehicle

Reattach the wheels and lower the vehicle off the jack stands.
Tighten lug nuts to the recommended torque specification.

5. Test Drive

Conduct a test drive to confirm that the popping noise has been resolved and that the suspension is functioning properly.
