Superdrive was acting up. I ordered a replacement from ifixit. Within a few days my order arrived. Installation took about 30 minutes, and the replacement worked perfectly.
Easy...thanks to the detailed guide on ifixit.
Just follow the directions. Keep all your screws organized and in order. There are several different sizes of screws that require removal. When you take the screws out, situate them so you know how they go back in.
