Since you replaced several front suspension components, I'd start by checking that all the bolts are properly tight.
A couple that seem likely are: frame to control arm bolt, strut to knuckle bolt, pinch bolt, and stabilizer link bolts.
Also, with the lower control arms, the pinch bolt that tightens the steering knuckle tight to the ball joint pin must be able to squeeze the gap down without any interference in the gap. I once had this problem where the gap was damaged keeping the pinch bolt from closing the steering knuckle down on the ball joint pin, and it seemed to cause a "pop" when turning, starting, and stopping.
It seems like it is something that is stable, until the lateral forces of a turn are seen.
