How do adjust/fix this leaking faucet?

I don't know what the brand/model of this faucet but it's leaking even if it's in the close position. How do fix this? It only leaks from the cold side...which is this turning handle.

Post a picture of the underside of faucet, showing the hose connections.
This might identity the manufacturer.

Is it leaking or dripping out the spout?

At first it was dripping and then all of the sudden it was pouring. I've looked at the underside of the sink everything was still tight. I started loosen everything and I'm starting to think that if there is a way to adjust the handle, it shouldn't be this hard to loosen everything underside the sink and take out the handle to adjust. Of course, I'm not a plumber so I could be wrong.

Used to be there was a washer that would need replacing to stop the drip/leak but modern day faucets don't have washers but use a valve [?] that you'd need to replace. You should be able to turn off the water and be able to remove the handle exposing the valve. You'd then just need to find a replacement, it would help if you can identify the brand.

The one you see it there is the leaking side. The other is the hot water side which you barely can see it from this shot.

Turn the water off under the sink, open up the valve to relieve the pressure and make sure the valve is holding.
On the back side of the valve there should be a hole where a allen wrench goes (it may be metric) handle pulls off straight up.
Once it's off you can see what's holding the cartridge in place.
There is no "adjusting it".

Right now the water is off. Is the valve referring to the handle that I turn the water on and off? There is no hole anywhere around this handle.

Yes, after you turn off the valve under the sink you turn on the water at the faucet to let any pressurized water out. Sometimes there is a decorative cap that hides the set screw, I don't know how your handle is attached.

The handle needs to come off to get to the valve cartridge.
Hold the handle and turn the bell housing under it.
Both hot and cold should unscrew CCW looking down.
These are the instructions and show clockwise for installation.

That looks exactly what I have. So there is nothing else to loosen it besides putting more force into turning the bell housing CCW, correct? I have tried and it won't budge at all. It looks like the whole unit is turning and not the handle. My guess is I have to tighten the valve underneath the sink harder so that when I turned CCW it won't turn the whole unit, correct? Just want to make sure I'm doing it right not ruining it more. Thank you so much for all the help.

The diagram I posted is Moen. I'm almost certain your faucet is Moen, only an older model made before quick-connect hoses.
Since there is no hole for a set screw, the housing must turn CCW.

Some customers ask to have their old faucets saved and it's not possible sometimes.
You should be able to get this apart but it's probably older than it looks and might not be worth it.

I'm afraid so. I even use a power-grip to turn but it will just turn the whole unit. I believed it has been around 25 years since it was built. Do you know of any similar styles to this one but a newer model?

Moen and Delta make quality faucets, there are others.

You have nothing to lose, the handle needs to come off even if you trash the faucet.
Have a helper hold the valve body with a wrench, from under the sink.
Wrap the bell with a course rag (heavy towel) and use a pipe wrench or large adjustable pliers.

Okay, so I finally have the time and got it to open. I found that this little plastic thing was broken.

Is this the replacement?

Moen 97479 Monticello Stem Extension Kit

I just found Moen 4570 on the back of the faucet. Could this be the model number? If so, does anyone know where I can get a new set of the dimensions of it? I don't see that Moen is selling this same model anymore. I have tried ordering a couple of faucets from Amazon but they're smaller than my current one.

Yes, 4570 is the model number.
You probably need both parts, Stem Extension 97479 and Handle Adapter Kit 100562.

If you want to order a new faucet, it needs to be a widespread. Widespread is three separate pieces like yours.
You are probably ordering a standard one-piece 4" on center faucet and that won't work.

Thank you for the detail explanations. I have three of these 4570 faucets from Moen. So, I'll probably have to purchase a whole set of new faucet for my other bathroom. Will this Moen T4560CP-9300 be the same size is the 4570?

No, the faucet you linked to will not work, the valve body that goes under the sink is fixed at 4" centers.

You need a widespread and Amazon isn't making it easy.
Here's one example of a widespread, Take notice that the hot and cold valves are connected with a hose under the sink. The hoses are what allows you to place the handles anywhere from 8 to 16" wide.

https://www.amazon.com/Moen-T4572-Mo...in%3A542680011

Here's another link directly to Moen:
Monticello Chrome/polished brass two-handle low arc bathroom faucet -- T4570CP -- Moen

There might not be a need to buy new faucets, your old faucets are guaranteed for life of the home.

Ah, thanks for that information.

Okay, so the valve system will have to be something like this one?

Moen 9000 Widespread Lavatory Rough-In Valve

So then, will this one, Moen Monticello T4570P 8" Lavatory/Bathroom Faucet, work?

Yes, that will work.
I think this faucet is discontinued though (I didn't know that), so get them while you can.

So even if I'm a new owner, the warranty still applies? Do I then contact Moen directly?

I'm not sure, It might be for as long as the purchaser owns the home.
Do you understand if you buy that faucet from amazon it doesn't include the rough-in kit?

I haven't dealt too much with Moen other than installation. Delta faucets has never asked me for a receipt, only an estimated purchase date if that, Moen is probably similar.

I would call Moen and see how many parts they offer, it might be all parts.

How do I know if the Moen Monticello T4570P 8" Lavatory/Bathroom Faucet is the same size as my current one since the model number is a bit different (T4570P vs just 4570)?

If I purchased discontinue items from eBay or Amazon, will I have the lifetime warranty from Moen?

We have beaten the horse to death. I don't mean to be rude.
A standard lavatory faucet is 4" spread and is not adjustable in width.
A widespread faucet can fit any distance between the hot and cold handles, as long as it's more than 4" and less than 16".

Okay, so I took my faucet out and this is what it looks like.

Is that threaded long tube there came off? If not, I don't see how the Moen 9000 Widespread Lavatory Rough-In Valve would work. If it does come off, how do I take it apart or tighten with the new one?

Second question, what is this part called and where do I get this part replaced? It looks like a filter that is threaded at the faucet spout.
