With the faucet shut off, take the handle off and under it is a nut around the stem. There is either an O ring under the nut, a fiber washer or stem packing depending on what type of faucet it is. Replace which ever it has and that should fix it. If your faucet is a screw type, the handle turns several time when opening it, you can probably take the nut off, wrap two or three wraps of stem packing around the stem, clockwise looking down on it and replace the nut and tighten. This will compress the packing around the stem without replacing the cone washer in the nut or all of the old packing.
It seems like if the nut went on first there'd be nothing to keep the washer on. Anyway, the the washer goes on a bolt before the nut.
the base of a cone is a circle you dumb nut
A lock nut should go on a bolt before a washer or the nut.

Spring washer - is used to keep the nut from loosening due to vibration by Appling pressure between the bolt and nut to stop it from undoing
Its called a Belleville spring/washer and it works by pressure. The washer is curved and when the nut is tightened down against it, the washer flattens out. But due to the heat treated memory of the metal, it wants to remain curved and pushes back against the nut which creates a locking effect between the threads on the nut and the threads on the bolt.
Jack up car, take off front wheel. Remove grease cap from center hub. Remove the large center nut, which really looks like a washer with 2 slots. Look carefully at nut/washer you will see a dimple in washer going into the axle shaft, you must take a drift and tap that back out so nut/washer will unscrew. Now here is what nobody will tell you : those nuts/washers will shatter like glass if you hit it to hard or wrong, i would get 2 of them { one for each side } before you start this project. After you get nut/washer unscrewed the hub will just slide off. Another tip the grease/dirt seal ,get 2 of them while you get the nut/washers, you will thank me later, trust me . Then either replace wheel bearings or clean and repack them. Then reverse procedure to put back together.
If it is dripping it is the washer, if it is coming out around the stem that is the packing needing to be replaced or some faucets have fiber cone in them that serves as packing around the stem. If your faucet is a 1/4 turn handle you need to turn the water off either at the sink or the main. If the handle screws in and out one or more complete turns you can do this with the water supply on. Shut the faucet off, remove the handle and any trim ring or cone under it that covers the stem sticking up. There should be a nut around the base of the stem. Unscrew this nut without turning the faucet on. In the nut underneath you will either have stem packing, which is a thick graphite or teflon string or a fiber cone. replace it with new and reassemble the faucet. If using packing and it still leaks after tightening, you can either tighten it a little more to compress the packing or just add a couple more layers of packing.
