I thought it would be a good idea to overhaul the hubs on my bikes. To start, I have a Trek 830 from 1994. The front hub is a Joytech with cups and cones. Pretty standard. I have serviced it once before. If you know anything about bikes you know this is a horrible terrible lack of maintenance. What can I say? I’m learning. The rear hub is a Shimano STX FH-MC32. It takes 1/4 inch bearings. The front is a Joytech hub and takes 3/16 inch bearings. These appear to be a kind of standard bearing size.

The rear was a pain in the ass. I think I messed up my dust covers taking them off and putting them on wrong.

Pro Tip! Get a string and tie a big washer or nut to one end. Then, as you take off the nuts, washers, cups and so on, from the axle, you will know how they went on and off. You could probably even degrease them right on the string so you aren’t an idiot like me and spend an hour or two trying to figure out how they go back.

Pro Tip! Take pictures of the stuff on and off the bike so you can see how it was to begin with. Makes it easier than spending an hour or two trying to figure it out like I did.

I’m getting some thin rubber gloves to wear because grease and stuff all over my hands is lame.
