I have some Deore LX M570 hubbed wheels that I'd like to service before I use them again. Can someone link me to a guide please?

the Park Tools website is pretty good for stuff like this

they're pretty straight forward, have you serviced a cup & cone hub before? If so, they're all pretty much the same

no have done hope before.

You'll need a set of cone spanners, grease, new bearings & cones ideally, plenty of rag & it's easy.
Disassemble from the non-drive side too, as you won't be able to do up the lock nut on the drive side when the axel is fitted.
Follow Pete's guide from here

as it's the same on your LX hubs. Bearing sizes aren't the same front & rear though
*edit* the only thing I'd do differently is to remove the disc first if you have them, to prevent the risk of getting any grease on them

thanks buddy thats great
