that faucet has been discontinued,to repair is very easy,pull off center cap,remove screw,handle comes off,remove center cap nut,remove clip,pull cartridge using moen tool,[home depot should loan one with a deposit ] install new cartridge with the hole in the brass part of the stem to the back of the sink,now while you are in there you might as well pull spout and change o-rings apply a little grease and put it back together.
hope this helps.Plumber Dave
