Guys,
I would like to make one correction in Neil's statement "the only
reason for the 'pulling' of the hub would be for a servicing of the axle
bearings, which are internally lubricated (right?), and which usually
only require "replacement"(?)."
This is not correct. There is an inner seal which prevents the differential
lube from flowing to the outer wheel bearings. The outer bearings are lubed
by removing a plug in the axel tube and injecting grease. If it hasn't been
done by the current owner, it may not have been done since the car left the
factory.

All right: 1st of all, you engineering-types (cept for Dave Homstad)
haven't exactly jumped in on this thread, that I'm hanging from.
Also, I was not present when my shop replaced Horrie's swaged brake
drum studs, which allowed the brake "drums" to slip-off of the
rear axles, without the necessity of using a
"wheel-puller" (any longer).
Welll, I went back to my shop, today, with my souvenir swaged stud (that
I keep in my office, for old-times-sake) and with the 2 WPC Club
articles that I authored (vols xviii/#7, 3/87 ; &
xxii/#2, 10/90), and told him to splain hisself.
He said that the central "hub" area is actually a SEPARATE piece, from
the ! outer "drum" section, and that the 2 pieces are held-together (thanx
to Chryco's renowned over-engineering)
by the swaged (press-fitted) 'shoulder-sections' of the studs that are
installed from/through the underside of the center-HUB section-piece. I
had been led to believe that the "swaged-studs" which prevented the easy
removal of the drums were the studs that are installed from the rear of
the AXLE-FLANGES: wrong!
Actually, the axle flange studs ARE 'swaged' into the flanges, but
they're not responsible for holding the hub/drum to the tapered axle (as
Lou & Dave have asked-about).
SO, once the hub/drum assembly is "pulled" off of the axle, the HUB
studs can be replaced with the 'standard round-shouldered' studs, so
that, once the hub/drum assembly is re-mounted to the tapered axle
(using copious "anti-seize lube" on the nexus of the hub & tapered
axle)
here it comes--------in the future, the "standard" round-shouldered
studs will allow the outer drum-section-piece to SEPARATE itself from
the hub-section-piece (which remains 'mated' to the tapered axle, and
which WILL require the use of a puller, to remove----however, the only
reason for the 'pulling' of the hub would be for a servicing of the axle
bearings, which are internally lubricated (right?), and which usually
only require "replacement"(?) .
ALL brake "servicing" can be performed with only the easy-removal of the
drum-section- piece, INCLUDING "turning" of the drums!
Now, "this" was the way that "the-deal" was splained to me.
Kinda interesting, huh?
