How do I Remove kitchen faucett?

I have an old single handle Moen kitchen faucett that is leaking. I want to replace it but looking at it for quite a while and can't be sure how to remove it. Wondering if any of you guru's would have the experience of this and tell me how it comes apart. I contacted Moen, but they didn't make any sense to me. I have included some pics so you know what I am talking about.

Thanks in Advance

Remove the nut on the bottom. You may need a basin wrench to do it.

As far as I can tell looking at it with the naked eye, it seems to be an integral part with the flat area that the 3 outlet/inlets go into. Am I mistaken in this?

It's a nut...turn it.

You will then have to disconnect the water supplies and the sprayer line, and 'massage' the three tubes closer together so you can drop off the nut and lift the faucet out from the top.

Moen sends free cartridges to replace the leaking part. Good to know about this if stopping the leak is your primary goal. You have to call Moen. If you want a new faucet anyway, the nut to loosen is visible in your last photo. It's underneath the counter. The tool mentioned by name above can be googled and youtubed.

It will probably be a lot easier to use a drill, or Dremel tool, and cut one side of the nut free, then pry it off the faucet.
