Tools Required: Jack and jack stands, socket set, torque wrench
Lift the vehicle and secure it on jack stands.
Inspect struts and shocks for signs of leakage or damage; replace if necessary.
Check control arms and bushings for wear; replace any damaged components.
Reassemble and torque all connections to the specified values.

4. Check Steering System

Tools Required: Socket set, torque wrench
Inspect the steering linkage for any loose or worn components.
Tighten any loose bolts, and replace worn tie rods or the steering rack if needed.
Ensure that all connections are secure and properly torqued.

5. Test Drive

Lower the vehicle and conduct a test drive to ensure the popping noise has been resolved.
Listen for any new or remaining noises and check the overall handling of the vehicle.
