Default Odd popping sound

Over the past 2-4 weeks my car started making a popping sound when I turn. It does not do it every time I turn. It sounds like it is happening on both sides in the front. The odd thing is that it will pop when I turn one way and then the side it popped on will not pop again until I turn the opposite direction and it will pop on the opposite side. I hope that makes sense. The first thing I think of is the sway bar because of how it alternates sides and depends on the direction I turn. I just had the oil changed and the guy who did it said he did not see anything broken or loose. Anyone else heard of this problem? Any part of the LS suspension that is prone to wearing out?

First make sure everything under there is tight. I would guess the CV joints are bad. If it were the swaybar, you'd feel very little lateral resistance even when turning a normal corner. It would feel like the car wants to wander sideways on every little curve at 35mph.
