How To Service Shimano Ball Bearing Hubs - Service A Shimano Hub
Ball bearing hubs can benefit from a regular overhaul. All Shimano hubs use ball bearings so we used one for our tutorial.

Regularly servicing ball bearing hubs will help to prolong the life-span of your hubs, especially if you regularly ride in gritty or wet conditions.
All Shimano hubs run on cup and cone bearings, so if you have Shimano wheels, this is a procedure that you should consider performing once or twice a year.
If your hubs feel like they are rough when you spin the wheels, or if there is play in the hubs, you could solve this issue by servicing the bearings.
If you're doing bearings on your rear hub, you'll need to take the cassette off first: https://www.youtube.com/watch?v=05WxxDo4CvY
For this job, you will need:
Cone spanners (we needed 13 and 17mm spanners for our hub)
Degreaser to clean the bearings and races
Grease
A tool to get the bearings out
A container to keep the bearings in whilst you clean the hub
Take care not to use degreaser in the rear hub as you risk degreasing the freehub if you do this. Also avoid overtightening the cones when you rebuild the hub as this will result in increased friction. The new grease may take a couple of days to settle/pack in, so check the cones for tightness a couple of rides after first servicing it.
