take the wheel off and what not
take the bearing cover off with a screw driver.
undo the locking pin and take off the nut.
then remove the hub and disk together
then from there there is a few bolts (4 i think) that hold the disk to the hub.
Remove them and you might have to tap the disk off with a hammer.
they are now off. obviously reverse to put it back together. make sure the hub nut isnt to tight.
