I just changed the one's on my girlfriends Durango, same thing except no locking tab (the hole was there on the arm, but not on the replacement wiper or the old one's). I recommend you replace the whole blade and spring/arm assembly. They're about $7 a piece from a parts store. If you take some rubbing alcohol and clean then, sometimes they will stop streaking so much for a while but most of the time it's little cracks and pits in the rubber that have worn and have to be replaced.
