How to replace your Cartridge Bearings

(This post was originally published on Projekt-B, and does not deal with Vallie Components Hubs)

In this post I'm going to detail the steps necessary to replace the cartridge bearings in your sealed hub. If you don't have sealed bearings, this doesn't apply to you.

How do you know if your cartridge bearings need replacement?

Well, for one, they will not spin as well and you will hear them. Secondly, they may develop side to side play even with the lock nuts tight. Thirdly, the seal may be wrecked, and they might be dribbling rust down your pretty high flange hub.
