It's pretty straight forward. mine was just as bad as they get.

First get the back end off the ground and take the tires off.
Remove the hub cotter pins and nuts 36mm and remove the hubs
Loosen the two bolts on the swingarm to free the carrier like you would do if you were going to adjust the chain.
Remove the brake caliper
turn the carrier and loosen the chain
remove the bolts that hold the sproket on. you can manuver the sproket around the hub and take it off
You can also take the chain off if you have a master link, otherwise just move it to the side.
On the caliper side there is a nut. The older ones are different but I think they operate the same.
tighten the nut a little so you can remove the C-clip from the groove then you can loosen it up and remove it.
Remove the brake rotor by sliding it out. You may have to knock it loose with a hammer and piece of wood. There is a rubber o-ring inside the rotor that may cause it to stick
Remove the snap ring that holds the caliper bracket on and then remove the bracket.
Now with everything lose you should be able to remove the carrier and axle out the sproket side.
support the carrier and with a hammer and wood hit the axle from the caliper side to knock loose the bearing. If this does not work you may need to use a press
Remove the old races from the carrier and replace with new ones. Use a driver to install the new races or a punch and hammer. Just be careful not to burr the races. A driver would be the best bet.
When installing the new bearings use a punch and a hammer and lightly tap them on.
Other than that just make sure you fill it up with grease and make sure you pack your bearings full of it before you install them.
I used marine grease in mine and it seems to work fine so far.

Hope this helps.
