shut water off at stops under sink. Unscrew water supply lines from directly below handles. Above them you will find plastic nuts, remove them. Disconnect pop/up lever and you should be able to lift faucet from sink.

On a Moen Faucet the set screw is behind the little "blue and red plastic tab", remove this tab very carefully with a small flat screwdriver. Then you should be able to see the set screw. make sure to turn of the water supply under the sink first. The set screw will probably be an "allen head" type and you will need an allen head wrench. This is a hex shaped 6-sided tool in a rod shape and is available at your local hardware in a set. Next you will need the model # of your faucet and take this to your local hardware to match with a repare kit. Moen usually has a lifetime warranty and if you have your paperwork just call Moen directly and they will send you a free replacement kit, free shipping too. The kit has installation instructions with it.
