I find one of the chrome decorative "spears" on my car, the right front fender bit, is loose at the rear end, and a potential rattle. With the RF wheel off and looking up inside the fender, I see two round pieces perhaps 1/4" long that somehow attach the spear. I was tempted to remove the panel inside the wheel well to better reach that location, but decided it likely wouldn't come out without a lot of work. So, are these round pieces threaded, and can they be snugged up enough to eliminate the potential rattle? The spear on the other side of the car is snug
