Typically, the metal transfers from one contact due to DC current, making it thinner and pitted. While replacing them both "while you're in there" is a great idea, the one worn contact makes the disk which connects the two get at too much of an angle on the center shaft of the solenoid to make a good contact. Once you get it apart you'll easily see what I'm trying to put into words.
