Remove wheel
if you've got to do the bearing the hub needs to come off
it will be easier if you undo the centre nut of the axle with the brakes still on as you can get someone to hold the brakes whilst you undo it, this should prevent the axle from turning
remove wheel
brake lines are 14mm union bolt i think, cant really remember you dont need to touch these unless your changing lines and or calipers .... standard caliper is held on with 2 x 17mm bolts iirc, whip those off and pull the caliper off, the disk should be ready to come free, it might be stuck firm so either use 2 bolts (not sure of the) size and wind them into the threaded holes in centre of disc to push against the hub, do each one abit at a time, or use my technique and get a big hammer
give them a whack and they're off.
If your going bigger discs the stone gaurd will catch, either cut it off or when you do the bearing take it off.
to get the hubs off...lock up the driveshafts, pull split pin from axle, take off the cover that stops the nut coming loose, theres one big bolt cant remember the size for sure, undo that, might be very tight
you will then need to split the 2 ball joints and undo the 2 bolts on the bottom of the strut and it should come off
The old bearing you can hammer out but the new one will need pressing in as you dont want to damage it.
probably forgotten something but thats the basics of it all
