I have a pop in the front left side of my 2013 SXT+. Mostly it pops when I turn the wheel left, I get about 5-7 pops at a time then 1-3 when I straighten out the wheel. Recently I replaced both the upper and lower control arm on that side. Replacing the control arms fixed all but one pop for about... 30 miles. Now it's back and worse than before. What is the other possible cause, it's very frustrating!
