OK my faucet has been leaking so I decided to replace the washers in the handles
Every diagram or picture I look at has a packing nut holding the stem down but mine doesn't it has a little pin stuck through the stem so I pulled that out but I still can't figure out how to get the stem out I'm not sure if I am supposed to pull it or unscrew it but neither seem to work
Thank you in advance

You don't have a stem, you have a cartridge.
