check underneath spout ... if is plastic then is a "less expensive" model and the base and some internal parts may be also made of plastic. Is it a model 7100,7400 or 7600? this appears on stem on opposite side of spout... The base may be "out of round" (or "eccentric") from many yearsand may continue to leak even after replacing bottom o-ring. I have learned that if the faucet is older and plastic, advise the person to invest the money in a new Moen faucet: if you are paying someone to do the work, save time & money by having them make the switch instead of tryting to fix w/ a new o-ring, if you want to try to dis-assemble faucet and replace o-ring:
While you are changing o-ring might as well replace cartridge, get cartridge form same place you get o-ring, cartridges are supposed to be free (depending on hardware store) ...someone there should be able to help w/ dissasembly .. i hope ..
Plug drain(s) add some warm water to sink to be able to wash and rinse parts if needed, shut water off, relieve pressure by turning tap on ... plug drains!!! (tiny screws love drains...)
Most MOEN single handles: just pull top off straight up, most are just press fit on. This exposes screw. Before taking screw out make sure you have a clear area to set parts in order of removal taking care to remember alignment and order. Remove screw ...
Internal parts are usually threaded plastic so go easy on things ... unscrew retainers, remove lever control making note on how it engages the cartridge etc... this helps you figure out re-assembly
pull entire spout housing straight up (might resist a bit if crudded up) hold up to light and see if out of round.. you'll now see the brass interior...pinch out o-ring and replace. Silicone lubricant may help (get from same place as o-ring, cart. they should have little free packs..) slide spout housing back over ... re-assemble all in reverse, do not over-tighten plastic retainers, hand-tight ok .. if still leaks
might want a new one ... hope this helps

The top pops off and there is a crew under it. It's all pretty easy but when you put it back together you have to do a tricky angle kick with the handle. Watch carefully as you take the handle off and put it on and off several times to see what is needed. If you do it wrong the handle sets on top of the black thing and doesn't work right, The cartridge in the faucet pulls out with difficulty if you have hard water. There is a little clip near the the top that holds the cartridge in. You should be able to get a repair kit that has the cartridge and new O-rings for the spout.

I had the same problem with my Aberdeen single lever with a pull-out sprayer a few months back. If you are the original owner of the faucet, it's under warranty; you shouldn't have to pay for any parts. Call: 1-800-BUY-MOEN (1-800-289-6636) and tell Customer Service what the problem is. They will send you the Handle Mechanism Kit at no charge. (Mine was part #93980 for my Aberdeen faucet, but yours may be a different part number.) It's tricky to take apart and get back together but my husband and I have zero plumbing experience and got it all fixed in about 20 minutes. The Moen.com website also has exploded parts diagrams of all their faucets so you can identify exactly what part you need, and they have some little videos and slideshows to show how to replace parts. If you can't reach Customer Service on the phone, you can go to "Contact Us" on their website and email them a description of your problem.

1. If it's "leaking" from the body then, the O-Rings between the body of the faucet got gunked up with minerals from your water. This interferes with the seal.
The answer is to take some grit cloth/very fine sandpaper and clean the inside of the spout body. Wipe clean. I would also suggest replacing the O-Rings on the faucet body, but at the very least wipe the O-rings and faucet body clean.
THEN: lubricate the inside of the spout body AND the O-Rings with silicone grease. It's translucent and readily available and the only thing I would ever use for a faucet repair. NOT plumber's grease, NOT WD-40.
Reassemble and enjoy.
2. If it's dripping, the you need a new cartridge. You can get them for FREE from the hardware store if you have the old cartridge to trade them. The problem is that Moen cartridges are water-sealed into place and you need a special tool to break that water seal. The special tool (just a tiny piece of specifically shaped plastic, really) comes, you guessed it - with the new cartridge.
Two possible solutions: a) bite the bullet and just buy the cartridge (~$25) or buy a Moen cartridge puller, usually available from the hardware store as well for about the same price. Ask, they might even lend you one.
The point of whichever tool you end up with is to rotate the cartridge itself inside the faucet body to break the water seal so that you can pull it out with a set of pliers. There will be a retaining clip to pull out as well.

Testimonial: "this will give me something to work on. thanks"
Replace the "O" rings that are behind the spout portion. You will have to remove the top of the faucet and pull up on the spout section. There will be a couple of "O" rings there. It is best to have Moen send the parts to you as locating the proper size "O" rings can be difficult.
