Solution

1. Preparation

Gather tools: socket set, torque wrench, jack, jack stands, and OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect Suspension Components

Sub-steps:
1. Use a jack to lift the front of the vehicle and secure it with jack stands.
2. Visually inspect the control arms, bushings, and struts for cracks or damage.
3. Press down on the front suspension to check for play in the components.

3. Check CV Joints

Sub-steps:
1. Examine the CV boots for tears or grease leakage.
2. If the boot is damaged, replace the CV joint or axle assembly as necessary.
3. If the joint is intact but making noise, consider replacing it.

4. Inspect Wheel Bearings

Sub-steps:
1. Remove the wheel and brake assembly to access the hub.
2. Grab the hub and shake it; any noticeable play indicates a bad wheel bearing.
3. If worn, replace the wheel bearing and seal.

5. Tighten or Replace Steering Components

Sub-steps:
1. Inspect the tie rods, steering rack, and any other linkage for looseness.
2. Tighten any loose fasteners to the manufacturer’s torque specifications.
3. Replace any worn or damaged steering components as needed.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Torque the lug nuts to the manufacturer's specifications.
3. Conduct a road test to verify that the popping sound has been resolved.
