Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Inspect Shock Absorbers and Struts
- Check for fluid leaks and signs of wear.
- If damaged, remove the strut assembly by loosening the top bolts and nuts and then the bottom mounting bolts.
- Replace with new struts or shocks as necessary.
Check Sway Bar Links and Bushings
- Remove the sway bar links by loosening the bolts at both ends.
- Inspect bushings for wear; replace if cracked or deteriorated.
- Install new sway bar links and torque to manufacturer specifications.
Examine Control Arms and Bushings
- Inspect control arms for damage and bushings for wear.
- If damaged, remove the control arm by unbolting it from the frame and the wheel hub.
- Replace with new control arms or bushings as needed and torque to specification.

3. Reassemble and Test

Reinstall any components removed during inspection.
Ensure all bolts are torqued to manufacturer specifications.
Reconnect the battery and perform a test drive to confirm the popping noise is resolved.
