As Chris said, the method listed in the service manuals that I have
seen is to jack up the car, take off the wheel/tire and remove the 4
bolts from the backing plate area (behind) that are holding on the
spindle/drum assy. Then pull off the assy. You will now have easy
access to the brake parts.
The bearing nut method may work too but is alot of torque I believe.
You may need a new nut too or it is only usable a few times.
I have not looked at mine yet as the fronts are still great, so I
can't comment on how it is to do. One thing that won't work for sure
is to pull the drum off without using one of the methods I mention
above to get it off.
