Yoda,
I believe it's called piston rod lock nut. When you open the hood and look at the top of the strut tower you will see a rubber cap in the center. Take it out and you will see the rod tip inside and the nut locking it. That's the one that does not let the rod to fall down.
Replacing it is good idea as if the shock is not covered it will wear sooner I believe as the dust and dirt can get inside easy. I paid $100 for all 4 dust covers - front and rear. I think the cover and the bumper is one thing. Though they are pictured separately in the manual.
