Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Suspension Components

Ball Joints:
- Inspect for play by moving the joint back and forth.
- If damaged, remove the old ball joint using a ball joint separator.
- Install the new ball joint, ensuring it is properly seated and torqued to the manufacturer's specifications.
Control Arms:
- Check control arm bushings for wear or cracking.
- Remove the control arm bolts using a socket set.
- Replace with new control arms if necessary, and torque the bolts to the specified values.

4. Check and Replace CV Joints

Inspect the CV joint boots for tears or grease leaks.
If damaged, remove the axle assembly by loosening the axle nut and disconnecting it from the hub.
Replace the CV joint or axle assembly, ensuring to properly torque the axle nut.

5. Reassemble and Lower Vehicle

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications.
Test drive the vehicle to ensure the popping noise is resolved.
