poping turns

Ball joint(s) are likely. As are tie-rod ends, stabilizer bar links, cv joints, and strut rod bushings.

If you can make it pop while the car is not moving, it's likely the ball joints. You can see the stabilizer bar links easily under the car with a flashlight or trouble light; if the rubber is beat out of them they will clunk on rough roads. You can jack the car up and check the front wheel firmness; if you can feel slack in the CV joint then it needs service. Also, if the CV joint boot has any break or leak at all, the CV joints will fail.

Check the strut rod bushings also

Since this noise is replicateable, a mechanic should be able to quickly locate this noise,

I would tell you how to locate it but, its dangerous and I would not want to get you hurt in the process

Ok, Ill tell you

Have someone sit in the car with it idling, in park and the emergency brake on, on a level surface.

Have them slowly turn the steering wheel back and forth with the window open so they can hear you while you put your head under the front and listen

Once you have localized the noise, put your hand on the lower control arm FROM THE FRONT away from the steering linkage, and see if you can feel the radiated noise, slowly and carefully feel and watch as the noise is made, feel and look for shifting of ball joints, strut rods, strut bearings, spring, keep your fingers OUT from behind bushings and control arms if they move and watch out for the tire moving back and forth.

BE CAREFUL, you have been WARNED and I will NOT be responsible, if you have ANY hesitation take it to a GOOD front end shop

Been there, done that, and it's scary as heck. Even scarier though is crawling under there with a flashlight while someone power-brakes the car, to determine which of your motor mounts is shot. I would never recommend that to anyone!

But yes, as Mike said, be VERY careful! It's quite easy to lose a finger when dealing with suspension parts.
