wow...
we sure live in different worlds .
I have run VW wheels and lug nuts and bolts of all sorts for going on 50
years...
have had wheels off and on literally MILLIONS of times..
currently own 7 good running vans ( got an 85 running project for sale
for not that much in So. Orgeon, btw ) ...
and about half a dozen other cars and rigs,
I'm swapping Ronal Mercedes wheels, South African 15 inch steelies
from van to van ...
I own about a hundred ( no kidding ) mounted and balanced wheels and tires,
and maybe at least a hundred extra lug nuts and bolts of various styles...
and sure...I do see some damage ..but it's usually from people being
sloppy ..
like lug wrenches that don't fit really right etc...
I have yet to see a stock steel wheel that won't work right at the
mounting point .
Or 'barely' if at all.
those flaws in the drums do look a little weird all right.
I saw one chinese made drum that had a Huge balance weight on it..
which was really glad to just fall off without much provocation.
Was new on a freshly purchased Westy ..I had to just toss it and put
something decent on.
I wasn't round either.
Generally the drums I get are european made ..often in Italy, or Germany.
I don't have problems with them.
I will say that 'workmanship' is worth about 70 % of the result one gets..
'It's not the Parts, it's the workmanship',
tho ya gotta use decent parts of course.
lol..I guess I'm going to die in a crash due to wheel failure since I
take my various wheels off and on a few times a year.
for 'regular people' ..if you do CAREFUL work ...very exacting careful
work actually ..
use plenty of appropriate products where indicated ..
mostly you'll be just fine,
though on brakes in general ...both disc and drum ...
it's not 'a given' they'll just fall onto the rig and be fine automatically.
Even pro shops have their tricks and run into difficulties at times.
To give you an idea ..I know one full time wheel/tire/brake shop that
turns ALL drums and discs ...even new ones out of the box.
Another guy I know ..same thing, full time pro ...he never resurfaces
any discs..
he puts pads on good discs, and new discs .
So yeah ...people who get good results on a regular basis with brakes
develop their own tricks and procedures to get their results.
heck , even driving break-in procedure matters.
for the life of me I can't imagine where that rule about 'never lube any
stud or wheel bolt treads.' Just doesn't make sense.
Maybe that's why some people have trouble with lugs nuts and wheels.
I guess I'm gonna die in a crash, since I put a tiny dab of ant-seize
compound on all wheel mounting threads and I've been doing that well
over 40 years..
have driven AT LEAST one million miles ( that's only 100K ten times
..not that much really ..
maybe I've driven 2 or 3 million miles ..)
and surely I must be due to die soon in a wheel-failure crash since I
lube my wheel mounting threads.
Just use yer brains and do careful work, and for sure..
expect that on most jobs that the very first time you do it ..
it will be a learning experience and may not 'automatically' work out
perfectly the first time.
I'm sure I'm gonna die on out on the road..
On my own personal vans ..I might even ( gasp ! ) replace just one shoe
that's more worn, or a leaky wheel cylinder without taking the shoes off.

You keep taking these things apart and you will need to replace the lug nuts and wheels due to them wearing out. Yes I have discarded wheels due to the seats reaching a point the lugs wouldn't hold. Lug nuts while very durable on the Vanagon in practice are not forever parts. After a number of cycles they don’t provide the same clamp load for a given torque.
