Just got my '12 R/T back from the body shop after the wife hit a deer 3 weeks ago. 6k damage to the left front. After driving it for about 2 hours yesterday, we heard a rattle in the left front, so I stopped to take a look. Didn't find anything, but there's a little stainless stud on the front of the upper control arm with nothing hooked to it. There's what appears to be a ride height sensor on the opposite side for the auto adjust headlights, but nothing on the left side stud. Is there supposed to be a sensor on both sides, or just the right? Couldn't see why Dodge would put the stud there if it has no purpose. Haven't heard the rattle since.
