The only problem using the 4 bolt removal system is that if you have never
had these bolts removed and reinstalled, it will be impossible to get then
loosened without using air tools. The lower shock mounting bolt has to be
also removed to get proper access. I live in a province where they used ice
melter on the roads and it rusts external car mechanical parts like crazy.
The only way to get the fasteners undone is to use a very large impact gun.
I just removed the spindle nut, and from what I found out so does most
dealerships and brake shops. The nut can be reused 4 times. Torque is about
160lbs.

Hi Garry
This has been discussed loads of times here before, if you Google in groups
you will find all the info you need.
Basically it is easier/better to remove the drums and hubs complete by
undoing the 4 bolts that hold them to the backplate. It gives you more room
to work and avoids disturbing the wheel bearings.

This argument comes up every time rear brake access is discussed! All I can
say is that I have used the 4-bolt method a number of times on both my
Focus, and on a number of Escorts (which have essentially the same brakes)
without a problem. It is the Haynes manual recommended way.
Cars with ABS need the sensor wire threaded through with a bit of care.
As a DIYer, I don't have access to any kind of impact gun. I just remove
them with a 13mm socket, short extention and ratchet - no problem!
I have never had to remove the lower shock mounting bolt - I can't see how
it is in the way unless there is a difference between US/European spec.
Removing the hub nut leaves the hub in the way, making shoe
removal/replacement much more difficult. It also runs the risk of wheel
bearing contamination or maladjusment on re-assembly.
Here in the UK salt is also used abundantly on the roads in winter but I've
never noticed it causing sufficient corrosion on fasteners such that
removal was impossible.
YMMV

I also live in such a winter climate, but if you get the car properly
undercoated such fastenings can be removed reasonably easily. An air gun is
useful, but a socket extension combined with a shot of anti-seizing spray
works just as well.
