IT'S the lower control arm 4sure...my made popping sounds off and on especially at stops at take-off, and also noticed it while driving slow turns as in parking situations. I let it go on for about 2 months, and then while parking at work, the whole front corner fell ontop of the tire. Lucky for me (a blessing from God), i wasn't on the street or godforbid the highway when it broke. It got towed to the shop and today i found out the tab is running me $386, which includes a 15mile tow charge.
Good Luck Silvreclips
