First off the wheel.
Next remove the six bolts holding the hub cover.....10mm I think.
Remove the cover marking its position so to refit the same.
You should now see the end of the drive shaft and its retaining circlip.
Remove the circlip and any shims behind it....keep safe.
Now remove the six bolts holding the hub. Get somebody to push the brakes as they are around 40 foot pounds.
Withdraw the hub.
Remove the brake caliper and tie up out the way.
Now you should see a plate with lots of holes and 3 screws 120 degrees apart.
Remove the screws......they are there to lock the plate and stop it turning.
When removed you will be able to tap the plate anti clockwise and then unscrew it by hand.
Remove the plate underneath, can be awkward because of the grease and stubby fingers.
But as the assembly is free you can retrieve it after you remove the main hub.
Grasp the disc both sides and pull the hub/disc off the spindle.
Retrieve the plate and inner race of the outer bearing.
You can now work on the hub/disc assy..ie change disc ,bearings and seals.
It sounds more complicated than it is and when you start it is a logical sequence.
Have fun
I'm pretty sure I haven't missed anything but if I have someone will jump in and correct
