This is a quick and easy guide to making those crunchy, loose, dirty, slow wheels feel like butter again! It'll take around 20-30 minutes for the beginner and faster once you get the hang of it.

A few things you'll need:
-Gloves (it gets dirty)
-Extra latex glove
-Cone wrenches that match your hub. Most are 13mm and 17mm, but they vary.
-Toothbrush (preferably your roommate's)
-Towel (preferably a clean washcloth, but paper towels are probably best since it'll be ruined the moment you use it)
-A clean, open workplace where you can find loose bearing balls that shoot off into the nevernever

You'll need some kind of cleaner for the grease, but I left this out because you can use damn near anything. The bearing balls are stainless steel, so you're not going to hurt them. I've used WD-40 for as long as I can remember, but I used windex this time and it worked fine. Residue isn't a real problem because you'll wipe them down on the paper towel before you put them back in.

Step 1: Get in There!

Once you have the wheel off your bike and the skewer (if you have one) is out of the axle, you'll want to loosen up one side (it might already be loose if your wheel was a little wobbly) and take the lock nut, any spacers, and the cone off. There might be a dust cover underneath. Mine has one. You can just gently pop it out with a wrench, knife, toothbrush, comb, key, toothpick, fork, bullet, used tungsten electrode, etc.

The axle is not held in with anything except those cones, so once you start to loosen them up, the bearing balls can fall out. The dust cover helps, but not all hubs have them and even with them the balls can fall out. You'll want the wheel sitting on the table while you do this so the axle is always pressed into the hub.
good instructable and well written with clear pictures :) I never though of using WD40 for cleaning bearings!<br> BTW when you take the cone and lock nut off, the easiest way is to hold the cone still and undo the lock nut. Don't try to unscrew the whole assembly. unscrewing the locknut while holding the&nbsp;<em>other</em> side still will make it more likely harder than needs be. Just pointing that out because it's the only thing that wasn't clear to me in the instructable<br> <br> oh yeah, what's that thing&nbsp;attached to the hub?
