Cleaning and repacking hubs is a little complicated, but not actually hard. If done correctly, it will prolong the life of your hubs. Problems are usually caused by worn bearings or the presence of water and dirt. Worn bearings can cause movement in the hub which makes the wheel rock side to side on its axle. Replace bearings every few thousand kilometres, or when the hub feels gritty or turns with difficulty.
