Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Raise the Vehicle

Use a jack to lift the front end of the vehicle.
Secure with jack stands for safety.
Remove the front wheels using a socket wrench.

3. Inspect and Replace Components

Suspension Bushings:
- Check bushings for cracks or deterioration.
- If damaged, remove the old bushings using a bushing removal tool.
- Install new bushings, ensuring they are properly seated. Use a lubricant as needed.
Ball Joints:
- Inspect ball joints for wear or looseness.
- To replace, detach the ball joint from the control arm and steering knuckle using a ball joint separator.
- Install a new ball joint, ensuring proper torque specifications (typically 35-45 ft-lbs, refer to specific service manual).
Struts/Shocks:
- If struts are identified as the source, remove the strut assembly by detaching it from the top mount and lower control arm.
- Replace with new struts and reassemble, ensuring all bolts are torqued to the manufacturer's specifications.

4. Reassemble

Reinstall the front wheels and lower the vehicle from the jack stands.
Reconnect the negative battery terminal.

5. Test Drive

Conduct a test drive to ensure the popping sound has been resolved. Listen for any remaining noises.
