or the hub:

Is it somewhat straightforward to replace?

as you have discs you need the hub, the bearing is not separate on them, they are on a drum brake model.

Cheers mate, thanks

Get a puller

+1 puller will make it easier, you can do it by knocking the pin back through the arm if not though

I'll borrow a puller from the mechanic next door :)
To get the new one on, i just use some grease and take a hammer and a piece of wood?
or take the old hub and hit on/though that?

slide hammerbolted to flange should get it off no probs

Thanks John

Just go steady braying the new one in
