You'll find cartridge or sealed bearing hubs on a lot of mid-high range wheels these days. If you have the right tools, it's a reasonably straightforward job - here's how to service them. Click here to subscribe to GCN: [ Ссылка ]

"If you notice that your wheel hubs are making a grinding noise, or if there's play in the axle, then it's time to have a look at the bearings. Types of hub fall into two categories. If your hubs use cup and cone bearings, check out this video: [ Ссылка ]

But if they're cartridge bearings, this is the video for you!


You may just need to clean and re-grease the ball bearings that sit inside the assembly. Just be careful not to damage the outer seal when you remove it.

However, if there is play in the axle, then replacing the cartridge is the way to go. We wouldn't recommend doing this without a specialist bearing puller and bearing press to push the new cartridges in. It can be a costly mistake if you get this wrong!
